... Cypress Semiconductor Corporation Document #: 38-04007 Rev Reprogrammable Registered PROM Functional Description The CY7C245A is a high-performance electrically programmable, read-only memory packaged in a slim 300-mil plastic or hermetic DIP. The ceramic package may be equipped with an erasure window; when exposed to UV light the PROM is erased and can then be reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms ...
