Key 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 using I2C command (Software STORE) or HSB pin (Hardware STORE).
RECALL to SRAM initiated on power-up (Power-Up RECALL) or by I2C command (Software RECALL).
Automatic STORE on power-down with a small capacitor.
High reliability.
Infinite read, write, and REC.
