GENERAL DESCRIPTION
The MX27C4000A is a 5V only, 4M-bit, One Time
Programmable Read Only Memory. It is organized as
512K words by 8 bits per word, operates from a single
+5 volt supply, has a static standby mode, and features
fast single address location programming. All program-
ming signals are TTL levels, requiring a single pulse. For
programming outside from the system, existing EPROM
