Abstract
Abstract Data is stored in one or more memory circuits of associated strobe drivers for providing strobe signal outputs during appropriate clock intervals of operating cycles. The memory circuits can be addressed through a read-wire (RAM) decode matrix. Each memory circuit includes internal circuitry for maintaining a stored voltage level throughout a cycle.
