A pure logic CMOS based low power non-volatile random access memory

A 1Kbits ultra-low power Non-Volatile Random Access Memory (NVRAM) based on 0.18μm pure CMOS logic process was proposed. This NVRAN features low power supply, low power consumption, high read speed and high reliability during read operation. The two-dimension array architecture and the high voltage solution contribute to the high area efficiency and application flexibility. The simulation result shows that the read speed can be 267Mb/s. The system´s read operation can perform well under the power supply of 0.7V with the read current of 66.4μA and the read power consumption of 906fJ/bit, while the read speed is still 51.3Mb/s, which is fully applicable in embedded or RFID system.
