47L64-I/SN More Semiconductors - ICs by Microchip Technology

64 Kb I2C Serial EERAM


EERAM is an SRAM that doesn't lose its content on a power disruption.  Inside each memory cell, transparent to the user, are nonvolatile transistors that capture the SRAM content and hold it through power loss events. On power restore, the SRAM is reloaded with its last content and SRAM operation can continue.
