A 3.3 V single power-supply 64 Mb flash memory with a DBL programming scheme has been developed and fabricated with 0.4 µm CMOS technology. 50 ns access time and 256 b erase/programming unit-capacity have been achieved by using hierarchical word- and bit-line structures and DBL programming scheme. Furthermore in order to lower operating voltage the HiCR cell is used. The chip size is 19.3 mm13.3 mm.
