Abstract: A column select multiplexer, a method of reading data from a random-access memory and a memory subsystem incorporating the multiplexer or the method. In one embodiment, the column select multiplexer includes: (1) a first field-effect transistor having a gate coupled via an inverter to a bitline of a static random-access memory array, (2) a second field-effect transistor coupled in series with the first field-effect transistor and having a gate coupled to a column select bus of the static random-access memory array and (3) a latch having an input coupled to the first and second field-effect transistors.
