Question

What is the main purpose of a sense amplifier? Draw the circuit of a sense amplifier and briefly explain its operation.

Answer 1

Main purpose is to sense stored data from a read selected memory (ram)

Step-by-step explanation:

When a memory cell being read produces a current Idata which moves some harvesters on charged bitline because of the presence of similar cells causing parasitic resistance and capacitance which causes voltage swing, sense amplifier Will translate this small voltage signal to a full logic signal for use.

NB: See attached document for diagram

Answer 2

The answer is "reading from RAM".

Step-by-step explanation:

SRAM and DRAM are two types of RAM (Random Access Memory) on electronic devices, the former stands for Static RAM and the latter for Dynamic RAM. There needs to be a reading and a writing function. Sense Amplifiers are involved in the "Read Circuitry" in this situation. They take on the role of "sensing" the low-power (logic 0) signals stored in the memory cells during the reading operation. Below is a circuit design of a basic sense amplifier. I hope this answer helps.
