FIFO Memory

FIFO, or first-in first-out, memory is a type of memory that is used to store data in a way that preserves the order in which the data was originally written. FIFO memory is commonly used in applications that require data to be processed in the order in which it was received, such as data communications or audio and video processing. A FIFO memory is typically implemented as a buffer, with a read pointer and a write pointer that are used to track the location of the oldest and newest data in the buffer. When new data is written to the FIFO memory, the write pointer is incremented, and when data is read from the FIFO memory, the read pointer is incremented. This ensures that the data is always read in the same order in which it was written. FIFO memory is typically implemented using integrated circuits, such as static random-access memory (SRAM) or dynamic random-access memory (DRAM).
