Features

256-Kbit nonvolatile static random access memory (nvSRAM).
Internally organized as 32 K × 8.
STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by user using HSB pin (Hardware STORE) or SPI instruction (Software STORE).
RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL).
Automatic STORE on power-down with a small capacitor (except for CY14B256Q1) High reliability.
Infini.
