Descripción:

Sylvania Electronic Components, Woburn, MA produced a 256-bit bipolar TTL ROM for Honeywell in 1965. Codes were programmed one bit at a time by physically scratching metal link connections to selected diodes. Also in 1965, General Microelectronics developed 1024-bit custom-mask programmed ROMs using MOS technology. By the early 1970s Fairchild, Intel, Motorola, Signetics, and TI offered 1024-bit high-speed bipolar ROMs, while AMD, AMI, Electronic Arrays, General Instrument, National, Rockwell and others produced 4096-bit (4K) MOS devices.
