Working Principles

IS42S16400D-7TLI operates based on the principles of synchronous dynamic random access memory. It stores data in a matrix of capacitors, with each capacitor representing a single bit of information. The module uses a clock signal to synchronize data transfer between the memory cells and the external system.

When a read or write operation is initiated, the module accesses the specific memory location by activating the appropriate row and column addresses. Data is then transferred through the data pins, enabling the processor to retrieve or store information.
