Working Principles

The IDT7164L20Y8 is a static RAM, which means it stores data as long as power is supplied. It uses a combination of transistors and capacitors to store and retrieve data. When a specific memory location is addressed, the corresponding data is read or written by controlling the appropriate control signals (CE1, CE2, WE, OE). The data is stored in flip-flops within the chip, allowing for fast access times.

Detailed Application Field Plans

The IDT7164L20Y8 is commonly used in various applications that require low-power, high-speed memory. Some typical application fields include:

1. Embedded Systems: Used as working memory in microcontrollers and microprocessors.
2. Communication Systems: Used for buffering and storing data in networking equipment.
3. Industrial Automation: Used for data storage and processing in control systems.
4. Medical Devices: Used for storing patient data and running real-time algorithms.
5. Automotive Electronics: Used in engine control units, infotainment systems, and instrument clusters.
