RADIATION HARD 8192 x 8 BIT MASK-PROGRAMMABLE ROM
The MA3864 64k Mask Programmable ROM is configured
as 8192x8 bits and manufactured using CMOS-SOS high
performance, radiation hard, 1.5µm technology.
The design has full static operation with no clock or timing
strobe required. Address input buffers are deselected when chip
select is in the HIGH state.
Programming is performed during fabrication by customising
the penultimate layer of the process. Programming data may be
supplied in EPROM or as a data file in the standard INTEL Hex
format.
