GENERAL DESCRIPTION
The K3S7V2000M-TC is a synchronous high bandwidth mask
programmable ROM fabricated with SAMSUNG′s high perfor-
mance CMOS process technology and is organized either as
4,194,304 x16bit(word mode) or as 2,097,152 x32bit(double
word mode) depending on polarity of WORD pin.(see pin func-
tion description). Synchronous design allows precise cycle con-
trol, with the use of system clock, I/O transactions are possible
on every clock cycle. Range of operating frequencies, program-
mable burst length and programmable latencies allow the same
device to be useful for a variety of high bandwidth, high perfor-
mance memory system applications.
