Abstract

A 125 mm2 1 Gb NAND flash memory with 10 MB/s program throughput was presented. The 1 Gb flash has the highest memory density among 2LC memories and the highest cell/chip efficiency among flash memories. Two techniques were adopted in the architecture for reducing the chip size, the number of memory cells in a NAND string was changed to 32 and each word line (WL) crossed (1024+32)×16 bit lines.
