SIMTEK STK12C68 Nonvolatile Static RAM Datasheet
The SIMTEK STK12C68 is a fast static RAM with a nonvolatile element incorporated in each memory cell. It supports unlimited read and write cycles while retaining independent nonvolatile data. The device features an 'AutoStore' function that automatically transfers SRAM data to nonvolatile elements upon power down, provided a capacitor of 68uF or larger is connected.

Questions answered in these manuals
What is the minimum capacitor size required for AutoStore?
A capacitor of 68uF or larger must be tied from Vcap to ground.
How many STORE cycles can the device perform?
The device supports 1,000,000 STORE Cycles to Nonvolatile Elements.
What does the STORE operation do?
STORE transfers data from the SRAM array to the non‑volatile elements, and can be initiated automatically on power‑down, by hardware, software, or the AutoStore™ feature.
What capacitor is required for reliable STORE on power‑down?
A capacitor of 68 µF or larger tied from Vcap to ground is required to guarantee the STORE operation regardless of power‑down slew rate.
What supply voltage does the STK12C68 require?
It operates from a single 5 V supply with a tolerance of ±10 %.

What is the data retention time when power is lost?
The non‑volatile storage retains data for up to 100 years without power.
