GENERAL DESCRIPTION
The K7A163601A , K7A163201A and K7A161801A are
18,874,368-bit Synchronous Static Random Access Memory
designed for high performance second level cache of Pentium
and Power PC based System.
It is organized as 512K(1M) words of 36(32/18) bits and inte-
grates address and control registers, a 2-bit burst address
counter and added some new functions for high performance
cache RAM applications; GW, BW, LBO, ZZ. Write cycles are
internally self-timed and synchronous.
Full bus-width write is done by GW, and each byte write is per-
formed by the combination of W Ex and BW when G W is high.
And with CS
1
high, ADSP is blocked to control signals.
Burst cycle can be initiated with either the address status pro-
cessor(ADSP) or address status cache controller(ADSC)
inputs. Subsequent burst addresses are generated internally in
the system′s burst sequence and are controlled by the burst
address advance(ADV) input.
LBO pin is DC operated and determines burst sequence(linear
or interleaved).
ZZ pin controls Power Down State and reduces Stand-by cur-
rent regardless of CLK.
The K7A163601A, K7A163201A and K7A161801A are fabri-
cated using SAMSUNG′s high performance CMOS technology
and is available in a 100pin TQFP package. Multiple power and
ground pins are utilized to minimize ground bounce.
