ABSTRACT:
A system for altering physical addresses of semiconductor memory cards to locate an error-free portion to provide a contiguous range of storage which is free from errors. The system contains a memory card ID register which stores the physical addresses of memory cards in positions corresponding to logical addresses. The system evaluates the results of routine tests of memory and rearranges the physical addresses stored in the memory card ID register to provide an error-free portion at the desired logical address range. A separate memory configuration register stores a value representing the size of the memory cards. The value stored in the memory configuration register selects a subset of the logical memory address bits to obtain a logical card address. The logical card address selects a position in the memory card ID register to obtain the physical address of the memory card.
