A static ram cell is described. The cell includes a pair of cross-coupled
transistors and a pair of diode-connected transistors operated from a
wordline that provides power to the cell. The cell has three main
operating modes, reading, writing, and data retention. Reading is
performed by sensing current flowing from a powered-up wordline through a
conductive one of the cross-coupled transistors. Writing is performed by
pulsing the source of the conductive one of the cross-coupled transistors
with a positive voltage to flip the conductive states of the
cross-coupled transistors. Data retention is performed by using leakage
currents to retain the conductive states of the cross-coupled
transistors. A decoder for an array of static ram cells may be operated
synchronously and in a pipelined fashion using a rotary traveling wave
oscillator that provides the clocks for the pipeline. The cell is capable
of detecting an alpha particle strike with suitable circuitry.
