Working Principles

IDT7164S20YI8 is a static RAM that stores digital information in a volatile manner. It uses flip-flops to store each bit of data, which requires continuous power supply to maintain the stored information. The chip enable (CE), output enable (OE), and write enable (WE) inputs control the read and write operations. When CE is low, the chip is enabled, and when OE is low, the outputs are enabled. Data can be written to the memory when both CE and WE are low. Reading from the memory occurs when CE is low and OE is low or high.

Detailed Application Field Plans

• Microcontrollers: Used as temporary storage for program instructions and data.
• Embedded Systems: Provides fast access to critical data in real-time applications.
• Communication Devices: Stores routing tables and buffers for efficient data transfer.
• Industrial Automation: Used for storing configuration settings and process data.
• Medical Equipment: Provides quick access to patient data and vital signs.
