The MX27C4111 is a 4M-bit, One Time Programmable Read Only Memory with page mode. It is organized as 512K x 8 or 256K x 16, operates from a single + 5 volt supply, has a static standby mode, and features fast single address location programming. All programming signals are TTL levels, requiring a single pulse. For programming outside from the system, existing EPROM programmers may be used. The MX27C4111 supports a intelligent fast programming algorithm which can result in programming time of less than two minutes.
