Working Principles

The 71V65703S75PFGI operates based on the principles of synchronous dynamic random-access memory (SDRAM). It stores data in a matrix of capacitors, organized in rows and columns. The row and column addresses are provided by the processor through control signals (/RAS and /CAS), and the data is read or written using the clock signal (CLK) and other control signals (/WE and /CS).

During read operations, the requested data is accessed from the specified row and column addresses and transferred to the processor. In write operations, the data is written to the specified row and column addresses, replacing the existing data.

Detailed Application Field Plans

The 71V65703S75PFGI finds applications in various electronic devices and systems, including but not limited to: - Personal computers - Servers - Networking equipment - Consumer electronics (e.g., televisions, gaming consoles) - Automotive electronics - Industrial control systems
