CY15B104Q-PZXI

CY15B104Q-PZXI is a low-power, 4-Mbit non-volatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is non-volatile and performs reads and writes similar to RAM. It provides reliable data retention for 151 years while eliminating the complexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other non-volatile memories. Unlike serial flash and EEPROM, the CY15X104Q performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after each byte is successfully transferred to the device. The next bus cycle can commence without the need for data polling. In addition, the product offers substantial write endurance compared to other non-volatile memories. These capabilities make the ideal for non-volatile memory applications, requiring frequent or rapid writes.
