Cypress Semiconductor F-RAM Excelon-LP Series

Cypress Semiconductor?F-RAM Excelon-LP Series?is low-power, 4Mbit nonvolatile?memory employing an advanced ferroelectric process. A ferroelectric random access memory (F-RAM) is nonvolatile and?performs reads and writes similar to a RAM. F-RAM provides reliable?data retention for 151 years. The devices?eliminate complexities,?overhead, and system-level reliability problems caused by serial?flash, EEPROM, and other nonvolatile memories.
