256-Kbit (32 K × 8) Serial (I²C) nvSRAM

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 (except for CY14MX256J1)
• High reliability
  • Infinite read, write, and RECALL cycles
  • 1 million STORE cycles to QuantumTrap
  • Data retention: 20 years at 85°C

Overview

The Cypress CY14MC256J/CY14MB256J/CY14ME256J combines a 256-Kbit nvSRAM with a nonvolatile element in each memory cell. The memory is organized as 32 K words of 8 bits each. The embedded nonvolatile elements incorporate the QuantumTrap technology, creating the world’s most reliable nonvolatile memory. The SRAM provides infinite read and write cycles, while the QuantumTrap cells provide highly reliable nonvolatile storage of data.
