[0060] see figure 2 , figure 2 This is a schematic flowchart of a multi-particle adaptive initialization method provided by an embodiment of the present invention. The multi-grain adaptive initialization method is applied to a solid-state hard disk. When the solid-state hard disk is powered on and initialized, the solid-state hard disk performs a multi-granular adaptive initialization method to realize the power-on initialization of different granules.
[0061] figure 2 It is a schematic flowchart of a multi-particle adaptive initialization method provided by an embodiment of the present invention. like figure 2 As shown, the method includes the following steps S110 to S140.
[0062] S110. Set the master control mode to an asynchronous mode.
[0063] After the FFh command and the 70h command are sent, the particle may be in synchronous or asynchronous mode. If the particle is in sync mode, the master and particle modes match, and the initialization is successful. If the particle is in the asynchronous mode, the master mode is the synchronous mode, and the master and particle modes do not match. Depend on Figure 5 and Image 6 As shown, in the asynchronous mode, the particle DQ[7:0] will send data out when RE# is low; while in the switching time mode, data will be sent out when RE# is asynchronous, as long as the frequency is low enough, the master control It is possible to interact using async mode and granular's async mode.
[0064] In the initialization phase, no matter what mode the particle is in, use the asynchronous mode for initialization, use the same set of codes and products compatible with different particles or different batches of the same particle, to improve the compatibility of the entire power-on initialization process and realize SSD multi-particle It is self-adaptive, no need to modify the configuration of the firmware, and the compatibility is strong.
[0065] S120, initialize the particles in an asynchronous mode.
[0066] In this embodiment, the main control is kept in the asynchronous mode and the frequency of the main control operating the NAND flash memory is less than 20MHz, preferably, the main control is kept in the asynchronous mode and the frequency of the main control operating the NAND flash memory is 10MHz
[0067] Keep the master in asynchronous mode and the master operates the NAND flash at a frequency of 10MHz; the particles may have Async (ie asynchronous serial)/Legacy/Toggle (ie the flash interface based on dynamic random access memory)/NV-DDR (ie non-volatile DDR interface)/NV-DDR2 (ie non-volatile DDR2 interface) mode, Legacy is a name for Toshiba particles, which has the meaning of asynchronous serial, Async/Legacy mode corresponds to SDR ( Asynchronous random, Synchronous Dynamicrandom) timing mode, Toggle/NV-DDR/NV-DDR2 mode corresponds to asynchronous timing mode. On the basis of analyzing the particle timing mode, in the particle initialization stage, the main control is kept in the asynchronous mode and the frequency of the main control operating NAND flash memory is controlled below 20MHz, generally 10MHz.
[0068] In one embodiment, as image 3 As shown, the above-mentioned step S120 may include:
[0069] S121, reset the particle according to the FFh command sent by the master;
[0070] S122, delay the setting time for the main control;
[0071] S123, judging whether the reset of the particles is completed;
[0072] If not, return to S122;
[0073] S124, if yes, send the 70h command to query the particle status by the master using the asynchronous mode;
[0074] S125, determine whether the particle state is a ready state;
[0075] If yes, then enter the S130;
[0076] If not, return to S124.
[0077] In this process, the difference from the prior art is that the 70h command is used to query the particle status in asynchronous mode. Regardless of whether the particle is in synchronous mode or asynchronous mode, data can be exchanged with the master to achieve the purpose of querying the particle ID.
[0078] S130. Obtain the particle ID.
[0079] In this embodiment, the particle ID is read according to the read ID command using the 00h address sent by the master.
[0080] S140. Switch the particle mode according to the particle ID.
[0081] In one embodiment, as Figure 4 As shown, the above-mentioned step S140 may include steps S141-S142.
[0082] S141. Obtain the particle manufacturer and product model according to the particle ID;
[0083] S142, switch the mode and the timing mode according to the method specified in the manual of the product model of the particle.
[0084] If it is a Micron particle, use the method specified in the Micron particle manual to switch the mode and timing mode; if it is a Toshiba particle, use the method specified in the Toshiba particle manual to switch the mode and timing mode.
[0085] The above-mentioned multi-particle adaptive initialization method, by setting the mode of the main control to asynchronous mode, and initializing the particles in this mode, and keeping the main control in the asynchronous mode and the frequency of the main control operating the NAND flash memory is less than 20MHz, to ensure that no matter what. No matter what mode the particle is in, it is initialized in asynchronous mode. It uses the same code and is compatible with products of different particles or different batches of the same particle to realize the self-adaptation of multiple SSDs without modifying the configuration of the firmware, and has strong compatibility.
