    • A memory system including ROM and RAM in which reading and writing are enabled. A memory system includes a non-volatile memory (FLASH), DRAM, a control circuit, and an information processing device. Data in FLASH is transferred to SRAM or DRAM in advance. Data transfer between the non-volatile memory and the DRAM 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.
    • 包括ROM和RAM的存储器系统,其中启用读和写。 存储器系统包括非易失性存储器(FLASH),DRAM,控制电路和信息处理设备。 预先将FLASH中的数据传送到SRAM或DRAM。 在非易失性存储器和DRAM之间的数据传输可以在后台执行。 包括这些多个芯片的存储器系统被配置为存储器系统模块,其中每个芯片相互层叠,并且每个芯片经由球栅阵列(BGA)和芯片之间的接合线布线。 FLASH中的数据可以通过保护FLASH中的数据可以在DRAM中复制的区域以及在接通电源或通过加载指令之后将数据传送到DRAM中,以与DRAM类似的速度读取速度。
