Fig. 1 is a schematic structural diagram of a chip timing adjustment device according to the present application, and it should be noted that the interaction relationship between the memory bank units 12 in fig. 1 is not described in the present application. In this embodiment, the chip timing adjustment device includes at least two memory modules 10, and the memory modules 10 include a timing balance unit 13 and a plurality of memory bank units 12.
A memory bank unit 12 for storing data.
Specifically, the chip timing adjustment device in this embodiment includes at least two memory modules 10, where the memory modules 10 include a timing balance unit 13 and a plurality of memory bank units 12, and it should be noted that the chip timing adjustment device in this embodiment further includes peripheral circuits including a row/column decoder, a sense amplifier, a read/write circuit, and other control circuits. In the present application, the data caching and storage functions are realized mainly by the storage module 10.
In the memory module 10, the timing balancing unit 13 is connected to the plurality of memory bank units 12, and the timing balancing unit 13 is configured to receive the timing signal, delay the timing signal, and fine compensate the timing signal, and transmit the delayed timing signal to the memory bank units 12.
Specifically, the timing balance unit 13 receives the timing signal, performs delay fine compensation on the timing signal, and transmits the timing signal to the memory bank units 12, so that the delays of the timing signal reaching each memory bank unit 12 are equal or identical as far as possible, and delay fine compensation of the timing signal between the memory bank units 12 in the chip memory module 10 is realized, wherein the delay compensation function of the timing signal between the memory bank units 12 implemented by the timing balance unit 13 is defined as delay fine compensation. The timing signal in this embodiment is a clock signal generated by a clock source of the chip. In other embodiments, the timing signal may be another timing signal such as a crystal oscillator signal.
In other embodiments, the delay of the timing balancing unit 13 in the different memory modules 10 is finely compensated, and the delay of the timing signal reaching each memory bank unit 12 is adjusted, which is not required to be equal or consistent as much as possible between the memory bank units 12 in all the memory modules 10, but may be that the memory bank units 12 in the different memory modules 10 receive the timing signals with different delays according to the requirements, which is not limited by the present application.
A memory bank unit 12 for storing data.
Specifically, each memory cell 12 is connected to other memory cells 12, wherein the horizontal direction connection is referred to as a "word line" and the vertical direction connection is referred to as a "bit line"; in accessing data, a specific word line and bit line can be selected by an inputted address, the intersection of the word line and bit line is the selected memory cell 12, and then the data access operation is performed on the memory cell 12.
Through the chip time sequence adjusting device, the time sequence balancing unit 13 is respectively connected with the plurality of memory bank units 12, the time sequence balancing unit 13 is used for receiving time sequence signals, and the time sequence signals are transmitted to the memory bank units 12 after delay fine compensation, so that the problem that in a chip array structure in the prior art, the time sequences of the memory bank units 12 at different positions cannot be balanced is solved, and the time sequences of the memory bank units 12 at different positions in a chip are balanced.
In some embodiments, the timing balancing unit 13 is configured to perform delay fine compensation on the timing signal, so that delays of receiving the timing signal by the memory bank units 12 at different positions in the memory module 10 are the same.
Specifically, the timing balance unit 13 is placed in the memory module 10 such that the distances from each memory cell 12 to the timing balance unit 13 are equal, thereby making the time of the timing signal from the timing balance unit 13 to each memory cell 12 equal. The time delay balance unit 13 performs time delay fine compensation on the time sequence signals, so that the time delays of the time sequence signals received by the memory bank units 12 at different positions in the memory module 10 are the same, and further the time delay balance of the time sequence signals among the memory bank units 12 in the same memory module 10 is realized.
In some of these embodiments, the chebyshev distance or euclidean distance between the timing balance unit 13 and the plurality of memory cells 12 is equal.
Specifically, as shown in fig. 1, when the distance between the timing balance unit 13 and the memory cells 12 in the memory module 10 is chebyshev, it is assumed that m memory cells 12 are in the whole chip, m is a positive integer greater than or equal to 9, each memory cell 12 is regarded as a target point, the m points are uniformly distributed in an array, and nine adjacent target points are selected as the memory module 10, respectivelyThen for each memory module 10, since the nine target points are uniformly distributed in an array, the chebyshev distances from the center point to the eight adjacent target points are equal, replacing the memory bank unit 12 of the center point position with one timing balancing unit 13. A coordinate system is established by taking the center point of the memory module 10 and the position of the time sequence balancing unit 13 as an origin, and the coordinate of the time sequence balancing unit 13 is +.>Let the coordinates of one adjacent target point be +.>The timing balance unit 13 to eight adjacent targetsThe Chebyshev distance of the punctuation can be expressed asBy equalizing the chebyshev distances of the timing equalization unit 13 and the memory bank units 12 in the memory module 10, and further controlling the time of the timing signals from the timing equalization unit 13 to each memory bank unit 12 to be equal, delay equalization of the timing signals between the memory bank units 12 in the same memory module 10 is achieved.
FIG. 2 is a schematic diagram of a chip timing adjustment device according to the present embodiment, as shown in FIG. 2, when the distance between the timing balance unit 13 and the memory cells 12 in the memory module 10 is Euclidean distance, it is assumed that n memory cells 12 are in the whole chip, n is a positive integer greater than or equal to 4, each memory cell 12 is regarded as a target point, the n points are uniformly distributed in an array, four adjacent target points are selected as the memory module 10, and the target points are respectivelyTaking the point at which the diagonals of the memory module 10 intersect as the placement position of the timing balance unit 13, the euclidean distances of the timing balance unit 13 to the four adjacent target points are equal. By equalizing the euclidean distance of the timing equalization unit 13 and the memory cells 12 in the memory module 10, and further controlling the time of the timing signal from the timing equalization unit 13 to each memory cell 12 to be equal, delay equalization of the timing signal between the memory cells 12 in the same memory module 10 is achieved.
By the two different definitions of the distances between the time sequence balancing unit 13 and the memory bank units 12 in the memory module 10, a time delay balancing scheme of the time sequence signal is correspondingly formulated, so that chebyshev distances or euclidean distances between the time sequence balancing unit 13 and the memory bank units 12 are respectively equal, and the diversity and flexibility of the time delay balancing scheme are further improved.
In some of these embodiments, the chip timing adjustment device further includes at least one timing compensation module 11, where the timing compensation module 11 is connected to the timing balancing unit 13 in the adjacent memory module 10; the timing compensation module 11 is configured to receive the timing signal, perform delay coarse compensation on the timing signal, and transmit the timing signal to the timing balancing unit 13 in the memory module 10.
Specifically, the delay compensation function of the timing signals between the memory modules 10 implemented by the timing compensation module 11 is defined as delay coarse compensation, and the timing signals after the delay coarse compensation are transmitted to at least one memory module 10 through the timing compensation module 11, so that the accuracy of the timing signals is ensured.
In this embodiment, the time delay compensation module 11 performs time delay coarse compensation on the time sequence signals, so that the time delays of receiving the time sequence signals by the memory modules 10 at different positions in the time sequence adjusting device are the same. In other embodiments, the time sequence signals with different delays may be received by different memory modules 10 after the delay coarse compensation according to the requirement, which is not limited by the present application.
In some embodiments, the memory module 10 is connected to at least one timing compensation module 11, and one of the connected timing compensation modules 11 can be selected to perform delay coarse compensation on the transmission of the timing signal by the memory module 10.
In some of these embodiments, the timing compensation module 11 is connected to at least one adjacent memory module 10 and is capable of selecting the timing compensation module 11 to be inactive, or active: the timing signal is received and is transmitted to at least one memory module 10 after delay coarse compensation.
Specifically, fig. 3 is a schematic structural diagram of a chip timing adjustment device according to the present embodiment, as shown in fig. 3, a timing compensation module 11 receives a timing signal output by a clock source, performs delay coarse compensation according to the timing signal, and transmits the timing signal to a memory module 10 to compensate for delay of the timing signal between different memory modules 10, thereby solving the timing adjustment problem of the memory modules 10 at different positions.
Specifically, the timing compensation module 11 receives the timing signal output by the clock source, and transmits the timing signal after the coarse delay compensation to the timing balancing unit 13 in the memory module 10, where the timing balancing unit 13 balances the delays of the timing signals between the memory bank units 12 in the memory module 10 according to the timing signal, so as to realize the timing balancing of the memory bank units 12 in different positions in the chip.
In some embodiments, the timing compensation module 11 is configured to perform coarse delay compensation on the timing signal, so that delays of receiving the timing signal by the memory modules 10 at different positions in the chip timing adjustment device are the same.
Specifically, the timing compensation module 11 performs coarse delay compensation on the timing signal, so that the delays of receiving the timing signal by the memory modules 10 at different positions in the chip timing adjustment device are the same.
In some of these embodiments, the memory cells 12 are distributed in a matrix configuration within the memory module 10.
In particular, the memory cells 12 are distributed in a matrix configuration within the memory module 10, and the array of memory cells 12 typically takes the form of a square or matrix to reduce the overall chip area and facilitate access to data. Taking a chip with a storage capacity of 4K bits as an example, a total of 12 address lines are required to ensure that each memory cell 12 can be selected. If the array of memory cells 12 is arranged in a stripe pattern comprising only one column, a 12/4K bit decoder is required, but if the array is arranged in a square pattern comprising 64 rows and 64 columns, only a 6/64 bit row decoder and a 6/64 bit column decoder are required, the row and column decoders may be arranged on both sides of the array of memory cells 12, respectively, with a total of 4096 intersections of 64 rows and 64 columns, each corresponding to a memory bit. When the memory cells 12 are arranged in a long stripe shape, the connection between the memory cells 12 and the data input/output terminal becomes longer, and the longer the connection is, the larger the delay on the connection is, so that the longer the connection is, the slower the read/write speed and the inconsistency of the connection delays of different memory cells 12 are caused. Therefore, the memory cells 12 are distributed in a matrix structure in the memory module 10, which can reduce the chip area and facilitate the access of data.
In some of these embodiments, the memory vault unit 12 includes at least one memory subunit.
In particular, the memory subunit in this embodiment is specifically SRAM (Static RAM), i.e. static RAM, which is composed of transistors. These transistors do not need to be refreshed, but lose information when shut down or powered off; SRAM operates very fast, typically at speeds of 20ns or more. One memory cell 12 includes at least one memory cell (bitcell), and the memory cells in the memory cell 12 share a control logic (control logic), and a plurality of memory cells form a memory cell array (bitcell), that is, the memory cell 12, for storing data.
In some embodiments, the timing compensation module 11 and the timing balancing unit 13 may be implemented by EMA (extra margin adjust, delay adjustment circuit), DCO (data controlled oscillator), RC (resistor capacitor circuit), or the like according to specific application scenarios and requirements.
The present embodiment is described and illustrated below by way of preferred embodiments.

In fig. 4, each timing signal is connected to the memory cells 12 along the timing signal in each memory module 10 to realize the transmission of the timing signal to each memory module 10, but the present application is not limited to the specific location of the connection to the memory cells 12, for example, the locations of the memory cells 12 connected to the memory modules B1/B4 are different; inside the memory module 10, the timing signals are transferred through control paths arranged along rows and columns between the memory cells 12.

It should be noted that, table 1 is a schematic delay value, and in practical applications, the delay values passing through different memory cells 12/memory modules 10 may be different, and may be obtained through simulation, and the embodiment shown in fig. 4 is only an ideal timing control device of a conventional chip.

In the preferred embodiment, 1 timing compensation module 11 is disposed between two adjacent memory modules 10, i.e. s1\s2\s6\s7\s11\s12 in fig. 5, and the memory modules 10 of the first row and the second row share one clock signal, and the memory modules 10 of the third row and the fourth row (not shown) share one clock signal, so that the timing compensation module 11 is disposed between the memory modules 10 of the first row and the second row, the third row and the fourth row (not shown), i.e. s3\s4\s5\s8\s9\s11\s12 in fig. 5, so as to avoid the problem that the timing compensation module 11 is insufficient.
The s1\s2\s6\s7\s11\s12 in fig. 5 may be moved to a position where the timing signals pass, that is, S3, S1, S6, S4, S2, S7, S5 are all disposed along the first timing signal line, and S8, S11, S9, S12, S10 are respectively disposed along the second timing signal line, so for convenience of drawing and description, the schematic of fig. 5 is adopted; in fig. 5, each time sequence signal passes through the corresponding time sequence compensation module 11 and then is connected with each memory module 10, so that coarse delay compensation is realized, and the delay reaching each memory module 10 is equal; the time sequence compensation module 11 is connected with the corresponding time sequence balancing unit 13 in the memory module 10, and the time sequence balancing unit 13 in the memory module 10 is reached after the time delay coarse compensation of the time sequence signal; the time sequence signals after the time delay coarse compensation are respectively transmitted to each storage library unit 12 after the time delay fine compensation is carried out by an internal time sequence balancing unit 13 in the storage module 10; in each memory module 10, the memory bank units 12 in the middle of the original positions are replaced by the placement time sequence balancing units 13, and the time sequence balancing units 13 are controlled to be equal to the chebyshev distance/Euclidean distance of each memory bank unit 12, so that the time sequences output from the time sequence balancing units 13 to the memory bank units 12 are equal, and the time delay fine compensation is completed; it should be noted that the present preferred embodiment is only an ideal improved chip timing adjustment device, and is only used to illustrate the timing compensation principle of the timing adjustment device of the present application, and the present application is not limited to the replacement of the placement timing balancing unit 13 with the originally placed memory bank unit 12, as long as the delay from the timing balancing unit 13 to each memory module 10 is ensured to be equal or consistent as possible.
