Embodiment 1
[0039] Such as figure 1 , figure 2 As shown, a method for realizing data protection of a non-volatile memory chip comprises the following steps:
[0040] Step 1: The PSU of the system power supply module is abnormal or powered off, and the PSU sends a power-off signal AC_Fail
[0041] to the programmable logic device of the system;
[0042] Step 2: After the programmable logic device receives the power-down signal AC_Fail, it triggers the asynchronous DRAM
[0043] The refresh signal ADR_Trigger# is sent to the PCH chip, the counter in the PCH chip starts timing, and the PCH chip transmits the received asynchronous DRAM refresh signal to the CPU through the power management synchronization signal PM_SYNC;
[0044] Step 3: After the CPU receives the refresh signal, refresh the data of the protection buffer ADR protected buffers to the DRAM of the non-volatile memory chip NVDIMM;
[0045] Step 31: After the CPU receives the refresh signal, it uses the rest of the filter cap...
