Abstract
A bit switch circuit (10) includes an amplifier stage (11) and a plurality of input stages (23,33,43,53). Each input stage (23,33,43,53) is connected to receive as inputs the signals applied to a bit line pair associated with a memory array. Each input stage (23,33,43,53) is also associated with a common node (24,34,44,54), and a select transistor (T4, T5, T6, T7). Each select transistor (T4, T5, T6, T7) responds to a select input signal to couple the respective common node (24,34,44,54) to ground. This allows the sense amplifier (11) to respond to the data signals on the bit line pair (20,21,30,31,40,41,50,51) associated with the respective input stage (23,33,43,53).
