Features & Applications

The CY14B101LA-SP45XI is a 1-Mbit fast Static RAM with a non-volatile element in each memory cell. The memory is organized as 128K bytes of 8 bits.

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.
