Features & Applications

The CY14B101LA-SP25XI is a fast static RAM, with a nonvolatile element in each memory cell organized as 128K bytes of 8 bits each or 64K words of 16 bits each.

The embedded nonvolatile elements incorporate QuantumTrap technology, producing the world’s most reliable nonvolatile memory. The SRAM provides infinite read and write cycles, while independent nonvolatile data resides in the highly reliable QuantumTrap cell. Data transfers from the SRAM to the nonvolatile elements (the STORE operation) takes place automatically at power down.
