3-Transistor Flash (3-Tr) is a new flash memory suited for embedded application. The 32 kByte memory cell has the low power erase/program characteristic of NAND flash, and the size of the cell fabricated in a 0.4 um NAND flash technology is 4.36 μm2. This is about 1/8 of the EEPROM cells size with the same design rule. Two circuit technologies, a low power sensing scheme and a double stage boosting scheme, are proposed. The sense scheme aims to reduce the power of the read operation without degrading access time. DSB, on the other hand, improves the power consumption property of the word line (WL) decoder during program mode.
