Abstract
A sophisticated bit-by-bit verifying scheme, which is able to realize a tight programmed threshold voltage distribution of 0.8 V, has been proposed for NAND EEPROMs. A new bit-by-bit verifying circuit is composed of a conventional sense amplifier and a dynamic latch circuit with only three transistors, increasing the chip size of the 64 Mbit NAND EEPROM less than 1%.
