A 3.6 ns 1 Kb ECL I/O BiCMOS UV EPROM

A 1 K-density EPROM with input and output levels available in ECL (emitter-coupled logic) 100 K or 10 K with a masking option is described. TTL (transistor-transistor logic) I/O (input/output)-compatible programming and verify modes allow the memory array to be programmed with standard EPROM (erasable programmable read-only memory) hardware and software. The EPROM is essentially two devices in one. It is an ECL ROM (read-only memory) with a high-speed ECL read path. The die can be configured to 100 K or 10 K ECL I/O level with a metal mask option. It is also a UV erasable and testable CMOS EPROM. The EPROM uses a standard TTL I/O programmer for programming and verification.<
