Working Principles

The AT27C512R-70RC utilizes a technology called electrically programmable read-only memory (EPROM). It stores data by using electrical charges to trap electrons in specific memory cells. These trapped charges represent binary values, which can be read by the system when needed.

During programming, a high voltage is applied to the appropriate pins, allowing the user to write data into the memory cells. Once programmed, the data remains intact until it is erased using ultraviolet light exposure.
