Signals and memory

Memory Array

  • A collection of memory cells or storage locations arranged in a grid-like structure

  • Each cell holds a bit of information, which can be either a 0 or a 1.

  • Cells are organized into rows and columns, with each row and column having a unique address.

Why Do We Use Memory arrays

Why do we use them

  • It allows for fast access and retrieval of data, which is essential for the efficient operation of electronic devices.

  • Memory arrays are designed to hold large amounts of information in a compact space

  • They are also highly reliable and stable. Memory arrays are designed to store data in a way that minimizes the risk of errors or corruption, which helps to ensure that the data remains intact and accurate over time

  • The memory array provides a means to store and access data in a systematic and efficient manner.

How do memory arrays work

How do they work

  • Memory arrays work by storing binary data in a series of memory cells that are organized into rows and columns. Each memory cell can store one bit of information, which can be either a 0 or a 1.

  • When data is written to the memory array, it is stored in the memory cells by changing the state of the cells from 0 to 1 or vice versa.

  • The location of the data within the array is determined by its address, which is usually represented as a binary number.

Types of signals

Signal Types

Write signals: sent from the processor to the memory array to write the image data to the memory cells. The write signals include the memory address where the data should be stored, as well as the actual image data that is being written.

Read signals: sent from the processor to the memory array to retrieve the image data from the memory cells. They include the memory address where the data is stored, and the memory array responds by sending the image data back to the processor for further processing or display.

Write = Saving

Read = Opening

Saving an Image

Saving an image

  • Data signals: Represent the actual image data that is being stored in memory. The data signals are binary signals that represent the pixel values of the image.

  • Control signals: Used to manage the transfer of data between the processor and memory array. Signals indicate whether data is being read from or written to memory, also indicate the start and end of a data transfer.

  • Address signals: Address signals are used to indicate the location in memory where the image data is stored. The processor sends the address signals to the memory array during the write operation to indicate where the image data should be stored, and during the read operation to indicate where the data is located.
