  1. In computing, memory refers to a device that is used to store information for immediate use in a computer or related computer hardware device. It typically refers to semiconductor memory, specifically metal–oxide–semiconductor (MOS) memory, where data is stored within MOS memory cells on a silicon integrated circuit chip. The term "memory" is often synonymous with the term "primary storage".

    What is computer memory?
    Computer memory is a temporary storage area. It holds the data and instructions that the Central Processing Unit ( CPU) needs. Before a program can run, the program is loaded from storage into the memory. This allows the CPU direct access to the computer program.
    What is the working memory of a computer system?
    Random access memory (RAM) is used as the working memory of a computer system. It stores input data, intermediate results, programs, and other information temporarily.
    What is the function of memory?
    It holds the data and instructions that the Central Processing Unit ( CPU) needs. Before a program can run, the program is loaded from storage into the memory. This allows the CPU direct access to the computer program.
    What is random access memory (RAM)?

    A byte of memory is used to store a code to represent a character such as a number, a letter or a symbol. Eight bits can store 256 different codes. This was thought enough and a byte became fixed at eight bits. This allows the ten decimal digits, 26 lower-case letters, 26 upper-caseletters and many symbols. Early comp…

      The memory cell is the fundamental building block of computer 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. The value in the memory cell can be accessed by reading it.
      In SRAM, the memory cell is a type of flip-flop circuit, usually implement…
