Working Principles

The IDT71256SA20YI is a static random access memory (SRAM) chip that stores data in a volatile manner. It utilizes flip-flop circuits to store each bit of information, allowing for fast and direct access to the stored data. The chip operates by enabling the appropriate control signals (CE, OE, WE) and providing the desired address inputs (A0-A14) to read from or write to specific memory locations. The data is then transferred through the data input/output lines (DQ0-DQ7).

Detailed Application Field Plans

  • Embedded systems
  • Networking equipment
  • Communication devices
  • Industrial automation
  • Automotive electronics
