CY15B104Q 4-Mbit Serial SPI F-RAM

Infineon Technologies CY15B104Q 4-Mbit Serial SPI F-RAM is a 4-Mbit non-volatile ferroelectric random access memory (F-RAM) logically organized as 512K×8. F-RAM is non-volatile and performs reads and writes similar to a RAM with reliable data retention of 151 years. The Infineon CY15B104Q eliminates the complexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other non-volatile memories.
