Working Principles

The PC28F064M29EWLA flash memory operates based on the principles of floating-gate transistors. It uses a grid of memory cells, where each cell stores data by trapping electric charge in an insulated floating gate. The presence or absence of charge determines the stored data value (0 or 1). To read data, the memory controller applies appropriate voltages to the selected memory cells and measures the resulting current flow. Writing and erasing operations involve applying higher voltages to modify the charge trapped in the floating gates.
