Reversible matrix-based memory SPD protection method

[0019] This embodiment proposes a memory SPD protection method based on an invertible matrix, and the specific implementation process includes:

[0020] Step 1: organize the memory SPD data into basic units according to the two-byte basic unit; further, organize the 512-byte memory SPD data into 256 basic units according to the two-byte basic unit; here , SPD: Serial Presence Detect, translated as the serial detection of the existence of the module, is a chip that checks the information of the existence of the module in the memory slot through the EEPROM of the IIC serial interface.

[0021] Step 2, apply transformation to each basic unit of the memory SPD data through the reversible matrix, and build it into the BIOS firmware in the form of memory SPD pseudo data;

[0022] Step 3: In the MRC of the BIOS, the memory SPD dummy data clearly expressed in the BIOS firmware is inversely transformed through an invertible matrix to obtain the real data of the memory SPD used for memo...
