CMOS DRAM
K4F171612D, K4F151612D
This is a family of 1,048,576 x 16 bit Fast Page Mode CMOS DRAMs. Fast Page Mode offers high speed random access of memory
cells within the same row. Power supply voltage (+5.0V or +3.3V), refresh cycle (1K Ref. or 4K Ref.), access time (-50 or -60), power
consumption(Normal or Low power) and package type(SOJ or TSOP-II) are optional features of this family. All of this family have CAS-
before-RAS refresh, RAS-only refresh and Hidden refresh capabilities. Furthermore, Self-refresh operation is available in L-version. This
1Mx16 Fast Page Mode DRAM family is fabricated using Samsung
s advanced CMOS process to realize high band-width, low power
consumption and high reliability. It may be used as graphic memory unit for microcomputer, personal computer and portable machines.

ABSOLUTE MAXIMUM RATINGS
* Permanent device damage may occur if "ABSOLUTE MAXIMUM RATINGS" are exceeded. Functional operation should be restricted
to the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.

NOTES
An initial pause of 200us is required after power-up followed by any 8 RAS -only refresh or CAS-before-RAS refresh cycles
before proper device operation is achieved.
Input voltage levels are Vih/Vil. V
IH
(min) and V
IL
(max) are reference levels for measuring timing of input signals.
Transition times are measured between V
IH
(min) and V
IL
(max) and are assumed to be 5ns for all inputs.
Measured with a load equivalent to 2 TTL(5V)/1TTL(3.3V) loads and 100pF.
Operation within the
t
RCD
(max) limit insures that
t
RAC
(max) can be met.
t
RCD
(max) is specified as a reference point only.
If
t
RCD
is greater than the specified
t
RCD
(max) limit, then access time is controlled exclusively by
t
CAC
.
Assumes that t
RCD
t
RCD
(max).
This parameter defines the time at which the output achieves the open circuit condition and is not referenced to V
oh
or V
ol
.
t
W C S
,
t
RWD
,
t
CWD
,
t
AWD
and
t
CPWD
are non restrictive operating parameters. They are included in the data sheet as electrical
characteristics only. If
t
W C S
t
WCS
(min), the cycle is an early write cycle and the data output will remain high impedance for the
duration of the cycle. If
t
CWD
t
CWD
(min),
t
RWD
t
RWD
(min),
t
AWD
t
AWD
(min) and
t
CPWD
t
CPWD
(min), then the cycle is a read-
modify-write cycle and the data output will contain the data read from the selected address. If neither of the above conditions
is satisfied, the condition of the data out is indeterminate.
Either
t
RCH
or
t
RRH
must be satisfied for a read cycle.
These parameters are referenced to CAS falling edge in early write cycles and to W falling edge in OE controlled write cycle
and read-modify-write cycles.
Operation within the
t
RAD
(max) limit insures that
t
RAC
(max) can be met.
t
RAD
(max) is specified as a reference point only.
If
t
RAD
is greater than the specified
t
RAD
(max) limit, then access time is controlled by
t
AA
.
t
ASC
, t
CAH
are referenced to the earlier CAS falling edge.
t
C P
is specified from the later CAS rising edge in the previous cycle to the earlier CAS falling edge in the next cycle.

If

.
For RAS-only refresh and burst CAS-before-RAS refresh mode, 4096(4K)/1024(1K) cycles of burst refresh must be executed
within 64ms/16ms before and after self refresh, in order to meet refresh specification.
For distributed CAS-before-RAS with 15.6us interval CAS-before-RAS refresh should be executed with in 15.6us immediately
before and after self refresh in order to meet refresh specification.
