Working Principles

The PC28F256P30T85A is based on NAND flash memory technology. It utilizes a grid of memory cells, where each cell stores multiple bits of data. The memory cells are organized into blocks, which can be individually erased or programmed.

During read operations, the requested data is retrieved from the memory cells and transferred to the output pins. Write operations involve erasing a block and then programming it with new data. The memory controller manages these operations and ensures data integrity through error correction techniques.
