Functional Description
The Cypress CY14C101J/CY14B101J/CY14E101J combines a
1-Mbit nvSRAM[2] with a nonvolatile element in each memory
cell. The memory is organized as 128K 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. Data transfers from SRAM to the nonvolatile
elements (STORE operation) takes place automatically at
power-down (except for CY14X101J1). On power-up, data is
restored to the SRAM from the nonvolatile memory (RECALL
operation). The STORE and RECALL operations can also be
initiated by the user through I2C commands.

Notes
1. The I2C nvSRAM is a single solution which is usable for all four speed modes of operation. As a result, some I/O parameters are slightly different than those on chips
which support only one mode of operation. Refer to AN87209 for more details.
2. Serial (I2C) nvSRAM is referred to as nvSRAM throughout the datasheet.
