Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
In a first aspect, referring to fig. 1, some embodiments of the present application provide a method for establishing a voltage of a chip, where the voltage is required for configuring a nor flash having at least two charge pumps, the method includes the following steps:
a1, acquiring the type of an operation command in the next stage when executing the current operation command;
a2, calling the operation voltage required by the idle charge pump configuration to execute the operation command of the next stage according to the operation command type of the next stage.
Specifically, in this embodiment of the present application, the current operation command is an operation command that is being executed by the nor flash, the next-stage operation command is an operation command that needs to be executed by the nor flash after the current operation command ends, different types of operation commands generally need to be configured with different operation voltages to execute, and both the current operation command and the next-stage operation command are bottom-stage operation commands in the nor flash, that is, bottom-stage commands that are independently completed based on the charge pump configuration related operation voltages set in the nor flash, for example, pre_program verify (ready to Program verify) in Program Strong (erase disturb repair command), PSrd0 (data 0 read), PSrd1 (data 1 read), ps_program repair), and other bottom-stage commands that are used as upper-stage commands, where each bottom-stage command needs to be independently configured with different operation voltages, for example, PSrd0 needs to be configured with corresponding operation voltages of data 0 read to determine whether threshold voltages of different memory cells are above the operation voltages to determine whether the memory data of the memory cells are data 0.
More specifically, in the embodiment of the present application, the nor flash has at least two charge pumps, which can perform voltage configuration (establishment, maintenance and output of operation voltages) independently and mutually non-interfering, and the nor flash only performs one type of operation command on the memory cell at the same time, that is, only one charge pump is used to provide the operation voltage, and the charge pump not used as the charge pump providing the operation voltage is regarded as an idle charge pump.
More specifically, the operation voltage required for executing the next-stage operation command in step A2 may be configured to start when the current operation command is executed, or may be configured to start when any stage of the current operation command is executed, so that the configuration of the operation voltage required for executing the next-stage operation command is started in advance in the process of executing the current operation command, so as to reduce the waiting time consumed for establishing the operation voltage in the process of operating the nor flash, thereby effectively improving the operating efficiency of the nor flash.
More specifically, for the complete upper-layer operation command, the operation voltage required by the first bottom-layer command cannot be established in advance, so the voltage establishment method of the chip in the embodiment of the application is mainly based on saving the waiting time required for establishing the operation voltage required by the whole of the plurality of bottom-layer commands continuously executed to improve the operation efficiency of the chip.
It should be noted that, in the embodiment of the present application, when the nor flash needs to execute the operation command of the next stage, the charge pump configured with the relevant operation voltage is selected as the operation voltage supply terminal through switching to execute the operation command.
According to the voltage establishing method of the chip, the type of the operation command to be executed in the next stage is determined during the execution of the current operation command, and the idle charge pump is called to configure the related operation voltage based on the type of the operation command to be executed in the next stage, so that the configuration of the operation voltage of the operation command in the next stage can be completed in advance by the nor flash, the waiting time required for establishing the operation voltage in the operation time sequence of the nor flash is reduced, and the operation efficiency of the nor flash is effectively improved.
In some preferred embodiments, the step of invoking the operating voltage required for the idle charge pump configuration to execute the next stage of operating command according to the next stage of operating command type comprises:
a21, acquiring configuration information according to the type of the operation command of the next stage;
a22, calling the operation voltage required by the idle charge pump configuration to execute the operation command of the next stage according to the configuration information.
Specifically, the magnitude of the operation voltage required by different operation commands of the nor flash is generally determined by configuration information obtained when the nor flash is powered on, so that corresponding configuration information obtained based on the type of the operation command characterizes related parameters of the operation voltage, and related operation voltages can be configured pertinently according to the configuration information.
After the current operation command is finished, the nor flash switching charge pump provides an operation voltage to complete a new stage operation command, the charge pump originally used for completing the current operation command is converted into an idle charge pump, the established operation voltage of the charge pump can be selectively released or maintained or changed, in the embodiment of the application, the established operation voltage of the charge pump preferably determines a configuration mode according to the type of a next stage operation command (i.e. a new next stage operation command) of the new stage operation command (i.e. a new current operation command), and the configuration mode can be to maintain voltage output or establish a new operation voltage; thus, in some preferred embodiments, the step of configuring the operating voltage required to execute the next stage of operating command comprises:
if the idle charge pump is configured with the operation voltage required by executing the operation command of the next stage, controlling the charge pump to keep outputting the voltage;
if there is no idle charge pump configured with the operation voltage required for executing the next stage operation command, controlling an idle charge pump to establish the operation voltage required for executing the next stage operation command.
Specifically, in this embodiment, the idle charge pump is originally configured with the operation voltage configured in the previous stage, which determines the configuration mode by determining whether the operation voltage required by the operation command in the next stage is consistent with the operation voltage, and when the operation voltage is consistent, the voltage output is maintained to skip the reestablishing process of the operation voltage, and for the case that the establishment duration of the operation voltage required by the operation command in the next stage is longer than the execution duration of the current operation command, the waiting time consumed for establishing the operation voltage in the operating process of the nor flash can be further reduced, so as to further improve the operating efficiency of the nor flash.
More specifically, as shown in fig. 2, in the Program Strong operation, it is required to alternately execute PSrd0 and PSrd1 operation commands, and during the execution, the two charge pumps maintain the output of the operation voltages required for executing PSrd0 and PSrd1, so that efficient alternate execution of PSrd0 and PSrd1 operation commands is realized through continuous charge pump input.
In some other embodiments, to avoid the problem of the charge pump maintaining output and increasing nor flash power consumption, the charge pump is switched to an idle charge pump release operating voltage, and the operating voltage required to execute the next stage of operating command is established.
In some preferred embodiments, the step of controlling an idle charge pump to establish the operating voltage required to execute the next stage of operating command comprises:
acquiring the residual operation time information and the establishment time information of the current operation command, wherein the establishment time information is the duration of the operation voltage required by the execution of the next-stage operation command;
if the remaining operation time information is greater than the setup time information, controlling an idle charge pump to start to establish the operation voltage required by executing the next stage operation command when the remaining operation time information is equal to the setup time information.
Specifically, the remaining operation time information is a remaining time required for completing the current operation command, and the voltage establishment method of the chip in the embodiment of the present application determines a start establishment timing of the operation voltage required for executing the next stage operation command by comparing the remaining operation time information with the magnitude of the establishment time information, so that when the overall time required for completing the current operation command is longer than the time required for establishing the operation voltage required for executing the next stage operation command, the establishment of the operation voltage is started at a proper timing, so as to reduce power consumption generated by maintaining output due to early completion of the establishment of the operation voltage, and enable the nor flash to directly switch the charge pump to execute the operation command of the next stage when completing the current operation command.
It should be noted that, if the remaining operation time information is less than or equal to the setup time information, the voltage setup method of the chip in the embodiment of the present application directly controls an idle charge pump to start to set up the operation voltage required for executing the operation command of the next stage.
In some other embodiments, if the remaining operation time information is greater than the setup time information, the voltage setup method of the chip of the embodiment of the present application may obtain delay start information according to the remaining operation time information and the setup time information, and control an idle charge pump to start to set up an operation voltage required for executing the operation command of the next stage according to the delay start information; in the embodiment, the idle charge pump is controlled to start to establish the operation voltage by setting the delay, and the magnitude relation between the residual operation time information and the establishment time information is not required to be continuously analyzed in real time.
In some preferred embodiments, the charge pump is based on a multiplexer connection.
Specifically, the multiplexer is a circuit device with a single output end and multiple input ends, and the output ends of each charge pump are respectively connected with one input end of the multiplexer, so that the nor flash can select the input source of the multiplexer according to the requirements to realize the switching function of the charge pump, and the multiplexer has the characteristics of simple structure and rapid switching response.
In some preferred embodiments, the charge pumps are two.
Specifically, based on the foregoing, it is known that the nor flash only executes one type of operation command on the memory cell at the same time, so that the two charge pumps can be switched to each other to meet the configuration requirements of the operation voltages of different operation commands.
In a second aspect, referring to fig. 3, some embodiments of the present application further provide a method for executing a command of a chip, which is applied to a nor flash for executing a continuous command, where the nor flash has at least two charge pumps, and the method for executing a command includes the following steps:
b1, acquiring the type of the operation command of the next stage when executing the current operation command;
b2, calling the operation voltage required by the idle charge pump configuration to execute the operation command of the next stage according to the operation command type of the next stage;
and B3, after the execution of the current operation command is finished and the operation voltage configuration required by the execution of the next stage operation command is finished, switching the charge pump to perform voltage input so as to provide the operation voltage required by the execution of the next stage operation command to execute the next stage operation command.
Specifically, the configuration duration of the operation voltage required for executing the next-stage operation command may be longer than the duration required for completing the current operation command, in this case, after completing the current operation command, the command execution method of the chip in the embodiment of the present application needs to wait until the operation voltage required for the next-stage operation command is configured, and then begin executing the next-stage operation command again; if the operation voltage required for executing the next stage operation command is already established in advance when the current operation command is completed, the command execution method of the chip in the embodiment of the application can directly start executing the next stage operation command.
According to the command execution method of the chip, the type of the operation command to be executed in the next stage is determined during the execution of the current operation command, and the idle charge pump is called to configure the related operation voltage based on the type of the operation command, so that the configuration of the operation voltage of the operation command in the next stage can be finished in advance by the nor flash, the waiting time required for establishing the operation voltage in the operation time sequence of the nor flash is reduced, and the operation efficiency of the nor flash for executing the continuous command is effectively improved.
More specifically, for a nor flash with only a single charge pump, after the nor flash executes some specific operation commands (such as ERASE), the charge pump still needs to Discharge (Discharge) and then reestablishes the operation voltage required for executing the next stage operation command.
In a third aspect, referring to fig. 4, some embodiments of the present application further provide a voltage establishment device of a chip, which is applied in a nor flash, for configuring a voltage required by the nor flash to perform an operation, where the nor flash has at least two charge pumps, and the voltage establishment device includes the following steps:
