Functional Description
The Cypress CY14V116N is a fast SRAM, with a nonvolatile
element in each memory cell. The memory is organized as
1024 K words of 16 bits each. The embedded nonvolatile
elements incorporate QuantumTrap technology, producing the
world’s most reliable nonvolatile memory. The SRAM can be
read and written an infinite number of times. The nonvolatile data
residing in the nonvolatile elements do not change when data is
written to the SRAM. Data transfers from the SRAM to the
nonvolatile elements (the STORE operation) takes place
automatically at power-down. On power-up, data is restored to
the SRAM (the RECALL operation) from the nonvolatile memory.
Both the STORE and RECALL operations are also available
under software control.
❐ STORE to QuantumTrap nonvolatile elements is initiated by
software, device pin, or AutoStore on power-down
❐ RECALL to SRAM initiated by software or power-up
■ High reliability
❐ Infinite read, write, and RECALL cycles
❐ 1 million STORE cycles to QuantumTrap
❐ Data retention: 20 years
■ Sleep mode operation
■ Low power consumption
❐ Active current of 75 mA at 45 ns
❐ Standby mode current of 650 A
❐ Sleep mode current of 10 A
■ Operating voltage
❐ Core VCC = 2.7 V to 3.6 V; I/O VCCQ = 1.65 V to 1.95 V

Note
1. In this datasheet, CE refers to the internal logical combination of CE and CE , such that when CE is LOW and CE is HIGH, CE is LOW. For all other cases CE is HIGH.
