Working Principles

The IS42S32800D-75ETLI operates based on the principles of synchronous dynamic random-access memory (SDRAM). It stores data in a matrix of capacitors, with each capacitor representing a single bit of information. The memory cells are organized into multiple banks, allowing for simultaneous access to different areas of memory.

When a read or write operation is initiated, the appropriate row and column addresses are provided to select the desired memory location. The data is then transferred between the memory module and the device's processor through the parallel interface.

To maintain data integrity, the memory module periodically refreshes the stored information using auto-refresh or self-refresh cycles. This ensures that the data remains valid even when not actively accessed.
