Before revision: Sense amplifier is part of the read circuitry that is used when data is read from the memory; its role is to sense the low power signals from a bitline that represents a data bit (1 or 0) stored in a memory cell, and amplify the small voltage swing to recognizable logic levels so the data can be interpreted properly by logic outside the memory.A Low-Power SRAM Using Bit-Line Charge-Recycling for Read and Write Operations, IEEE Journal of Solid-State Circuits, 2010 IEEE Modern sense-amplifier circuits consist of two to six (usually four) transistors, while early sense amplifiers for core memory sometimes contained as many as 13 transistors.PDP-8 Maintenance Manual, Digital Equipment Corporation, F-87, 2/66, 1966; page 10-9 drawing RS-B-G007.
