The WM71004 WM71008 WM71016
is a family of RFID
tag ICs with nonvolatile Memory
employing an advanced ferroelectric process. A ferroelectric random access Memory
or F-RAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 20 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM
and other nonvolatile memories. Unlike EEPROM?s, the WM710xx write operations are zero power ? there is no power or speed premium paid for executing writes into the WM710xx as compared to read power and speed. Operation of the Memory
is fully symmetric: identical read and write characteristics in terms of power, speed, and reliability.
