What is STK11C68?


This is 8K x 8 nvSRAM QuantumTrap CMOS Nonvolatile Static RAM.

Static RAM (SRAM) is a type of computer memory that uses flip-flop circuits to store each bit of data. Unlike dynamic RAM (DRAM), which needs to be refreshed many times per second, SRAM retains its data as long as power is supplied to the circuit. SRAM is typically faster more than DRAM.
