... Document Number: 001-06400 Rev Mbit (128K x 8) nvSRAM Functional Description The Cypress CY14B101L is a fast static RAM with a nonvolatile element in each memory cell. The embedded nonvolatile elements incorporate QuantumTrap technology producing the world’s most reliable nonvolatile memory. The SRAM provides unlimited read and write cycles, while independent, nonvolatile data resides in the highly reliable QuantumTrap cell ...

... SRAM. In addition, it provides unlimited RECALL opera- tions from the nonvolatile cells and up to one million STORE operations. SRAM Read The CY14B101L performs a READ cycle whenever CE and OE are LOW while WE and HSB are HIGH. The address specified on pins A determines the 131,072 data bytes accessed. ...

... V is less than V HRECALL CC If the CY14B101L WRITE mode (both CE and WE are low) at power up after a RECALL or after a STORE, the WRITE is inhibited until a negative transition detected. This protects against inadvertent writes during power up or brown out conditions. ...

... The six consecutive address locations are in the order listed HIGH during all six cycles to enable a nonvolatile cycle. 2. While there are 17 address lines on the CY14B101L, only the lower 16 lines are used to control software modes state depends on the state of OE. The IO table shown is based on OE Low. ...
