A 55-nm, 0.86-Volt operation, 125MHz high speed, 75uA/MHz low power, wide voltage supply range 2M-bit split-gate embedded Flash

Firstly a high-speed and low-power sense amplifier is implemented in 90-nm embedded Flash (64KX32) design based on split-gate Flash bitcell with good correlation of 90uA/MHz power and 50MHz speed in wide voltage supply range (VDD=0.86~1.32V, and VD33=1.6~3.6V). It shows less process dependent speed by design approach. In further 55-nm node, it demonstrates competitive features by post layout simulation with more competition of faster operation speed up to 125MHz (VDD=1.08V) but still keep merits of low-power read (75uA/MHz, 32 bits) and wide range supplies on both read and write (VDD=0.86~1.32V, and VD33=1.6~3.6V).
