How do logic gates store memory?

The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level). Its value is maintained/stored until it is changed by the set/reset process.

What is the main purpose of the logical gates?

Logic gates are used to make decisions so that electrical outputs only ‘turn on’ when the correct logic sequence has been applied. Each logic gate has a name that helps to describe how different inputs will determine the possible outputs .

Can logic gates be used to store data?

The ability to store binary data is critical to the operation of computer systems as well as to other digital circuits. The simple circuits that have been examined so far – NAND, OR, the adder circuits – all are combinational logic circuits: their outputs are purely a function of their inputs.

How do memory circuits function?

Memory circuits function by storing the voltage present on an input signal whenever they are triggered by a control signal. They retain that stored voltage until the next assertion of the control (or trigger) signal.

Which two gates are used to construct one bit memory?

We can create one bit memory by using two logic NAND gates. Here when both inputs are given as logic 0 the output goes to undefined (Q, Q’) and the both inputs are given as logic 1 the output remains no change.

Which gate can store 1bit of data?

A very simple Set-Reset flip flop can be made from discrete components using two transistors and four resistors arranged as a bistable. This will store 1 bit of information.

What logic circuit would you use for addressing memory?

An address decoder is a particular use of a binary decoder circuit known as a “demultiplexer” or “demux” (the 74154 is commonly called a “4-to-16 demultiplexer”), which has many other uses besides address decoding.
