Working Principles

W972GG6JB-3I operates based on the principles of dynamic random access memory (DRAM). It stores digital information in a matrix of capacitors, where each capacitor represents a single bit of data. The stored information needs to be periodically refreshed to maintain its integrity.

When a read or write operation is initiated, the chip activates the appropriate row and column addresses to access the desired memory location. Data is then transferred between the chip and the device's processor through the input/output pins.

Detailed Application Field Plans

The W972GG6JB-3I chip finds extensive use in various electronic devices and systems, including but not limited to: - Personal computers - Laptops - Servers - Mobile phones - Tablets
