GENERAL DESCRIPTION
The KM616V1002B is a 1,048,576-bit high-speed Static Ran-
dom Access Memory organized as 65,536 words by 16 bits.
The KM616V1002B uses 16 common input and output lines
and has an output enable pin which operates faster than
address access time at read cycle. Also it allows that lower and
upper byte access by data byte control (UB, LB). The device is
fabricated using SAMSUNG′s advanced CMOS process and
designed for high-speed circuit technology. It is particularly well
suited for use in high-density high-speed system applications.
The KM616V1002B is packaged in a 400mil 44-pin plastic SOJ
or TSOP2 forward.

NOTES(READ
CYCLE)
1. WE is high for read cycle.
2. All read cycle timing is referenced from the last valid address to the first transition address.
3. t
HZ
and t
OHZ
are defined as the time at which the outputs achieve the open circuit condition and are not referenced to V
OH
or
V
OL
levels.
4. At any given temperature and voltage condition, t
HZ
(Max.) is less than t
LZ
(Min.) both for a given device and from device to
device.
5. Transition is measured
±200mV
from steady state voltage with Load(B). This parameter is sampled and not 100% tested.
6. Device is continuously selected with CS=V
IL.
7. Address valid prior to coincident with CS transition low.
8. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle.
