摘要

A 512-Mb flash memory, which is applicable to removable flashnmedia of portable equipment such as audio players, has been developed.nThe chip is fabricated with a 0.18-Μm CMOS process on an126.6-mm2 die, and uses a multilevel technique (2 bit/1ncell). The memory cell is AND-type, which is suitable for multilevelnoperation. This paper reports new techniques adopted in the 512-Mb flashnmemory. First, techniques for low voltage operation are described. Thencharge pump, control of pumps, and the reference voltage generator arenimproved to generate internal voltage stably for multilevel flashnmemory. Next, a method for reducing total memory cost in the removablenflash media is described. A new operation mode named read-modify-writenis introduced on the chip. This feature makes the memory system simple,nbecause the controller does not have to track sector-erase information
