Description of the Invention (i) The present invention pretends to open a dynamic memory memory, especially about the fast page mode dynamic memory memory (Fast Page node DRAM, FPD for short). ) And Extended Data-Out DRAM (EDO), when the user simultaneously applies the fast page mode to dynamically record 100 million bytes and the extended output dynamic memory 100 million in the same computer system, the system can Easily check it out in order to set different operating configurations and improve the overall performance of the system. The dynamic memory system is currently the most commonly used computer system in the system, and the entire structure is composed of rows / columns of 100 million units in the form of a matrix. Therefore, it is necessary to use a column address and a row address to designate a certain to-be-recorded 100 million cell when operating dynamic memory, and then read or write data. That is, when the general dynamic memory is used to access the data, the column address flash control signal ΰ! Is first lowered to trigger the reading of the column address, and then the row address flash control signal is reduced to low. The potential is used to trigger the capture of the row address, so that the hundred million units to be processed are specified, and then the data can be accessed using the output / input data line DQ. However, in order to improve the operation speed, the dynamic memory manufacturer also provides a page mode access mode. The operation mode is limited to the page boundary defined by the column address, which is called the fast page mode. The operation mode of dynamic page memory in the fast page mode is different from the conventional one. After the column address flash control multiplying ^ drops to a low potential to trigger the reading of the column address, the entanglement remains low. , And only change the flash address signal of the row address to a low state so as to read the data of the same column address. When the column address flash control signal returns to high level, the fast page mode ends. Although the dynamic page-recording mode of the fast page mode has been the current standard dynamic-recording mode, the performance in terms of speed has been unsatisfactory, especially ---------------- --- Order-\ ----- line (please read the notes on the back ^ P to fill out this page) This paper size applies to China National Standard (CNS) A4 (2 丨 OX297 mm) Central Standard of the Ministry of Economic Affairs A7 B7 printed by the Bureau ’s Consumer Cooperatives V. Invention Description (2) The new generation of human computers, such as Intel Pentium, is even more prominent. Therefore, some manufacturers of dynamic memory memory, such as Micron, HEC, Sansung, Toshiba, etc., have formulated a new page model of dynamic memory memory, which is called extended output dynamic memory memory. The extended output dynamic memory model and the fast page model dynamic memory model have the same pin configuration and most of the timing characteristics. The difference lies in the time held by the data on the rotation / input data line DQ. In the fast page mode, the data on the output / input data line DQ of dynamic memory will close its buffer with the rising edge of the address flash control signal, but the extended output dynamic memory will not. Figures 1 and 2_ are the timing diagrams for reading data in the fast page mode for dynamic memory counting and extended output dynamic memory counting, respectively. In Figure 1, Clock is the central processing unit clock signal and READ is the capture signal. Since the pre-charging time ten of the row address flash control signal ϋΙ 必须 must be performed when the input / output data line DQ is invalid, each reading action interval is 3 値 the central processor clock cycle; in Figure 2, the line The pre-charging time tc of the address flash control signal 〃 is not performed when the input / output data line DQ is invalid data, so each read operation only needs to be spaced 2 clock cycles from the central processing unit. This will lead to a significant increase in the operating speed of dynamic memory. However, the user may be on the same motherboard, while using the fast page mode to dynamically record billions of characters and extended output to dynamically record billions of characters. As far as the II brain system is concerned, as long as the two are placed in different banks, the current system has the ability to give the best mode of operation based on the timing of dynamic banks. Otherwise, even if the computer system is inserted with a faster extended output dynamic memory, in order to ensure the accuracy of the data, the overall speed must be ^ ^ unn ^ n J n line (please read the notes on the back first and fill in (This page) This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) A7 B7 5. Description of the invention (3) The speed is based on the dynamic recording of the fast page mode. Therefore, as long as the two types of dynamic memory are set up in different memory groups, and the system can be distinguished, the efficiency of system resources can be fully exerted and the overall speed can be improved. The method of directly distinguishing the fast page mode and the extended output dynamic memory is to write a piece of test data into the dynamic memory to be tested, and then use the extended output dynamic memory to record the faster time series. The dynamic memory is the extended output dynamic memory, and the fetching data and writing data will be exactly the same. If it is fast page mode dynamic memory, it will fetch errors due to too fast speed. The above methods can be easily achieved using software. However, in practice, the conventional method is prone to discriminating errors. The reason is that the stray capacitance on the external wire of the input / output data line DQ of the dynamic memory register is lost. When the DQ of the dynamic memory register of the fast processor in the fast page mode disappears after the rising edge of the row address flash control signal, but Due to stray capacitance, it is possible that the data on the input / output data line DQ will not completely disappear, and it will still linger for a considerable time (more than 20 ns). Even if the timing of the dynamic output of the billion-byte reading is extended, it is still possible to write in accordance with the read data and cause errors.

The invention description (4) is an extended output of the dynamic memory of billions, the test method includes the steps of: writing at least one test data in the dynamic memory of billions; In the fast page mode, the input and output data line sends the test data, and then the input and output data line is discharged; the input and output data and online data of the material line are read; thereby, when the online data and the test When the data is consistent, the dynamic record of the billion body is the extended output dynamic Recalling the body, when the line data and the test data are inconsistent, the body is a dynamic memories Fast Page Mode Dynamic memories body. In addition, the present invention also provides a dynamic memory counting method for determining whether a dynamic memory recording is a fast page mode dynamic memory recording or extended output dynamic memory recording. The test method includes the steps of writing at least one The test data is stored in the dynamic recorder; in the reading operation, when the input and output data lines of the dynamic recorder are sent out, the test data is delayed for an appropriate time; the online data of the input and output data lines are read; Therefore, when the online data is consistent with the test data, the dynamic memory is the extended output dynamic memory. When the online data is inconsistent with the test data, the dynamic memory is the fast page mode dynamic memory. . In order to make the above-mentioned objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is given below in conjunction with the accompanying drawings to make a detailed description as follows: A brief description of the formula: FIG. 1 is fast Timing chart of page mode dynamic recording of billion-body grabbing action.

Description of Invention (5) First embodiment: In this embodiment, it is determined that the dynamic memory counting is a method of dynamically recording the billion memory in the fast page mode or extending the output of the dynamic memory recording. First, a set of test data is written into the dynamic memory recording to be determined. Next, read the data to determine the operation.谪 Refer to FIG. 3, which shows a timing chart for discriminating the reading test data in the first embodiment. When the row address flash control signal falls to the falling edge of the low potential at the high threshold, read the address of the dynamic memory that has been stored in the test data; when the row address flash control signal rises to the high potential at the low potential When the rising edge of the input, the input and output data lines DQ in the dynamic digitizer specified by the address ADR send the correct test data. After a period of time, the DQ of dynamic memory of billions of pages in the fast page mode is changed to invalid data. The extended output of dynamic memory of billions of hours can maintain valid data until the next reading period. The method used in the first embodiment is called the plug-in waiting method, that is, when the consumer address of the Central Standards Bureau of the Ministry of Economic Affairs of the Ministry of Economic Affairs of the Ministry of Economic Affairs of the Bank of China is printed (please read the notice on the back and fill in this page). The time that the signal must wait for reading, so that the fast page mode dynamically records the data that is affected by the stray capacitance of the motherboard and becomes invalid data. For example, in the general fast page mode, the dynamic signals of the 100 million body and the extended round-out of the 100 million body are inserted as X-3-3-3 and X-2-2-2, which means that data is captured every 2 and 3 boat cycles. In the test phase in this embodiment, the read signal insertion can be set to X-7-7-7 or greater. Therefore, the insertion waiting mode in this embodiment can be achieved by soft palate. In addition, the delay time 必须 must be set differently on different motherboards to account for the effects of stray capacitance caused by different motherboards. Second embodiment: The method used in this embodiment is called the forced discharge method. In the same way, this paper size applies to the Chinese National Standard (CNS) A4 (210X297 mm) A7 B7 Printed by the Central Bureau of Standards of the Ministry of Economic Affairs-Industrial and Consumer Cooperatives i. Invention Description (6) A set of test data, and then taken out for comparison. When the row address flash control multiplier is at the rising edge of low potential to high potential, the input and output data line DQ of the dynamic memory of the billion body is the correct test data. At this time, the system changes the state to 0 on the other end of the input and output data line DQ. If the dynamic memory is in fast page mode, the output buffer is closed, so the potential on the stray capacitance will be Decline and become invalid. On the other hand, if the dynamic digitizer is the extended output dynamic digitizer, the effective data can be maintained because the output buffer has not been closed. Finally, after reading the online data, compare with the original test data to determine the type of dynamic memory. Similarly, this embodiment can also be implemented by software. The main points of the present invention are as follows: 1. The insertion waiting method and the forced discharge method used in the present invention can effectively prevent the stray capacitance from being judged. 2. The implementation mode can be executed by software or BIOS program, suitable for modification test in general computer system, and automatically establish the correct configuration of dynamic memory. Although the present invention has been disclosed as above in the preferred embodiment, but its It is not intended to limit the present invention. Any person skilled in the art will not deviate from the spirit and scope of the present invention. Some modifications and retouching can be made. Therefore, the scope of protection of the present invention shall be regarded as the scope of the attached patent. The ones defined shall prevail. ----: --.----- Packing I .1 (Please read the notes on the back to fill in this page first) Threading This paper size applies the Chinese National Standard (CNS) A4 specification (210X2.97 mm)
