    摘要: A memory system including large-capacity ROM and RAM in which high-speed reading and writing are enabled is provided. A memory system including a non-volatile memory (CHIP1), DRAM (CHIP3), a control circuit (CHIP2) and an information processing device (CHIP4) is configured. Data in FLASH is transferred to SRAM or DRAM in advance to speed up. Data transfer between the non-volatile memory (FLASH) and DRAM (CHIP3) can be performed in the background. The memory system including these plural chips is configured as a memory system module in which each chip is mutually laminated and each chip is wired via a ball grid array (BGA) and bonding wire between the chips. Data in FLASH can be read at the similar speed to that of DRAM by securing a region in which the data in FLASH can be copied in DRAM and transferring the data to DRAM in advance immediately after power is turned on or by a load instruction.

    摘要: To enhance the speed of first access (read access different in word line from the previous access) to a multi-bank memory, multi-bank memory macro structures are used. Data are held in a sense amplifier for every memory bank. When access is hit to the held data, data latched by the sense amplifier are output to thereby enhance the speed of first access to the memory macro structures. Namely, each memory bank is made to function as a sense amplifier cache. To enhance the hit ratio of such a sense amplifier cache more greatly, an access controller self-prefetches the next address (an address to which a predetermined offset has been added) after access to a memory macro structure so that data in the self-prefetched address are preread by a sense amplifier in another memory bank.
