东芝是全球生产NAND闪存的主要供应商,最近该公司推出一种改进的NAND闪存,称为“芯片处于不关心模式(Chip Enable Don’t Care)”的NAND闪存,它允许微处理与存储器总线及I/O上的其他设备通信,同时NAND处于“读数据忙”状态。这种NAND闪存克服了高级手机存储方案中集成NAND要求增加设计工作量和需要粘胶逻辑(glue logic)或综合存储总线的缺点,使低成本的NAND闪存可应用于高级手机。其中TC581282AXB容量为128Mbit,TC582562AXB容量为256Mit,供电电压均为3.3 V。
Toshiba, the world’s leading supplier of NAND flash memory, recently introduced an improved NAND flash memory called “NAND flash memory with Chip Enable Do not Care”, which allows both micro-processing and Memory bus and other devices on the I / O while NAND is in the “read data busy” state. This NAND flash overcomes the shortcomings of integrating NAND in advanced handset storage solutions that require increased design effort and the need for glue logic or integrated memory buses to enable low-cost NAND flash memory to be used in advanced handsets. Including TC581282AXB capacity of 128Mbit, TC582562AXB capacity of 256Mit, the supply voltage is 3.3V.
