I think all of you heard the word "Memory". There are many books and blogs where you can learn about the details of memory. Even some of you already know about Memory. But are you know how a Semiconductor Memory is designed. In this post, we are going to learn about the only basic concept of  Memory in Digital circuits and the Internal structure of Semiconductor memory.


Semiconductor Memory in Digital Circuit: 

             Memory is a device that can store data in the form of a binary. Semiconductor memory refers to the electronic storage devices that are used as primary memory in the computer and other electronic devices. Most of the semiconductor memory is used Random Access Memory(RAM) because it has much faster access times than other types of data storage devices. ROM (Read-Only Memory) is also an example of semiconductor memory. 

Semiconductor memory is based on the use of integrated circuits (ICs) that contain numerous memory cells, each capable of storing a bit of information (0 or 1). The fundamental concept behind semiconductor memory involves utilizing the electrical properties of semiconductors, typically silicon, to create memory cells that can be easily accessed and manipulated. These memory cells are organized into an array, forming the memory structure.

                                              See the above diagram. The basic structure of memory is given in the above figure. As you see the above figure the memory is consisting of a no of registers. Each register consists of no of Flip-Flops. In the below figure, each register consists of 8 Flip-flops. Flip-flops are made by Logic Gates. And Logic gates are made by the transistor. So actually each bit of any binary data is stored in a flip-flop. It is also called a memory cell.

             We already have known that a Flip-flop circuit can store one-bit data which means 0 or 1. So the whole memory is made by flip-flop circuits. As you see each register has 8 flip-flops so one register can store 8-bit or 1-byte data. In the majority of Memory Cards, each register has 8 flip-flops.
Each register is indicated by a location that is called a memory location or address. You can see according to the above figure the memory address starting from 0000 to FFFF.

I hope you understood the concepts of Semiconductor Memory in Digital Circuit. The internal structure of Semiconductor Memory.

Semiconductor memory supports both read and write operations. Reading involves accessing the stored data from a memory cell, while writing involves modifying or updating the data in a specific memory cell. Also, remember that the semiconductor memory can be either volatile or non-volatile. Volatile memory, such as RAM, requires a continuous power supply to retain stored data. Non-volatile memory, such as ROM or flash memory, retains data even when power is removed.
