Logic-compatible embedded NVM for RFID application

Abstract

In this paper, we described the design of logic-process compatible embedded non-volatile memory (NVM) macro for the application of radio frequency identification (RFID). A prototype 1024-bits NVM test chip fabricated by 0.18 mum standard CMOS process is described and characterized. The characterization result shows write power is only 90 uW for write operation and 2 uW @0.5 MHz for read operation. The minimum VCC for read operation can be as low as 0.68 V at -40degC. Macro size of 1024-bits IP is only 0.215 mm2.
