... PROMs are erased and can then be reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms. The CY7C261, CY7C263, and CY7C264 are plug-in replace- ments for bipolar devices and offer the advantages of lower power, superior performance and programming yield. The EPROM cell requires only 12 ...
