Abstract
Multiplexer control logic is provided for a semiconductor memory device that combines the function of programmable disconnect-state with a dynamic or dynamic latching mode that operates during self-refresh. The programmable disconnect state disconnects the sense amplifier from a memory array segment when it is unselected. When a memory array segment is being accessed, (such as during self-refresh), the multiplexers are latched into a selected state thereby eliminating the multiplexer switching current while the memory array segment is being accessed.
