Working Principles

The AT29LV040A-20JC utilizes a floating-gate transistor technology to store data. It employs a grid of memory cells, where each cell can store a bit of information by trapping or releasing electric charge in the floating gate. The presence or absence of charge determines the stored data value (0 or 1). The memory cells are organized into an array, and the address lines control the selection of specific cells for read or write operations. The control signals (/OE, /CE, /WE) manage the timing and functionality of the memory access.
