Claims (1)

[Claims for Utility Model Registration] (1) In a storage device that is equipped with a plurality of memories and has a plurality of banks that can be accessed in an interleaved manner and can be expanded, interleaved access can be performed for each access memory address corresponding to the expanded memory. an instruction means for instructing either non-interleaved access; and memory access means for converting the memory address into an interleaved access address or a non-interleaved access address to obtain a real memory address based on an instruction from the instruction means. A variable interleave control storage device comprising: (2) Utility model registration In the variable interleave control storage device described in claim 1, the instruction means includes a selection means for generating a selection signal for selecting the bank based on the access memory address; determination means for determining whether or not the interleave access is possible based on the interleave permission signal set in advance and the selection signal for each case, and outputting a determination signal, the memory access means converting the determination signal into the instruction A variable interleave control storage device, wherein the memory address is received as the interleave access address or the non-interleave access address. (3) Utility model registration In the variable interleave control storage device described in claim 1, which is used at the time of initialization, all of the memories are initialized by non-interleaved access, and the A variable interleave control storage device comprising: a setting means for setting whether or not interleave access is possible; and a determining means for diagnosing the memory and detecting unimplemented memory and malfunctioning memory to determine the memory capacity.
