Next high performance and low power flash memory package structure

In general, NAND flash memory has advantages in lowpower consumption, storage capacity, and fast erase/write performancein contrast to NOR flash. But, main drawback of the NAND flash memoryis the slow access time for random read operations. Therefore, weproposed the new NAND flash memory package for overcoming this majordrawback. We present a high performance and low power NAND flash memorysystem with a dual cache memory. The proposed NAND flash packageconsists of two parts, i.e., an NAND flash memory module, and a dualcache module. The new NAND flash memory system can achieve dramaticallyhigher performance and lower power consumption compared with anyconventional NAND-type flash memory module. Our results show that theproposed system can reduce about 78% of write operations into theflash memory cell and about 70% of read operations from the flashmemory cell by using only additional 3KB cache space. This valuerepresents high potential to achieve low power consumption and highperformance gain.
