if the memory initialization in the DIMM slot is normal, the programmable logic device controls the state indicator lamp corresponding to the DIMM slot to be in a lighting state, clears the register state data stored in the storage area, and unloads the SMI program of periodic memory processing;

if the memory initialization is not completed when the periodic time interval of the SMI program arrives, the memory bank initialization is considered to have a fault, the periodic SMI interrupt is triggered, the SMI program of periodic memory processing is executed, the memory of the fault DIMM slot is forbidden, the next DIMM slot is pointed, the data of the register state in the memory area is read, the SMI program is exited, and all register values are restored to the values of the registers read by the memory area;

a check is made for memory in the next DIMM socket.

8. An easy-to-repair recycling design method for a memory bank, characterized by being applied to an easy-to-repair recycling design system for a memory bank according to any one of claims 1 to 7, comprising:

s1, testing and acquiring the use state of each memory chip on the memory bank, wherein the use state comprises a normal use state and a fault state;

s2, when detecting that at least one memory chip on the memory strip fails, automatically shielding the corresponding memory chip with the failure and enabling the memory strip to be used normally.

9. A computer device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, implements the steps of the easy repair recycling design method for memory sticks as claimed in claim 8.

10. A computer-readable storage medium storing a computer program, wherein the computer program when executed by a processor implements the steps of the easy-repair recycling design method for memory banks according to claim 8.
