HY51V64164,HY51V65164
4Mx16, Extended Data Out mode
1st Generation
DESCRIPTION
This family is a 64M bit dynamic RAM organized 4,194,304 x 16-bit configuration with Extended Data Out mode CMOS
DRAMs. Extended data out mode is a kind of page mode which is useful for the read operation. The circuit and process
design allow this device to achieve high performance and low power dissipation. Optional features are access time(60 or
70ns) and refresh cycle(8K ref. or 4K ref.) and power consumption (Normal or Low power with self refresh). Hyundai’s
advanced circuit design and process technology allow this device to achieve high bandwidth, low power consumption and
high reliability.
FEATURES
Ÿ Extended data out operation
Ÿ Read-modify-write capability
Ÿ Multi-bit parallel test capability
Ÿ LVTTL(3.3V) compatible inputs and outputs
Ÿ /CAS-before-/RAS, /RAS-only, Hidden and
Self refresh capability
Ÿ JEDEC standard pinout
50-pin plastic TSOP-II (400mil)
Ÿ Single power supply of 3.3 ± 0.3V
Ÿ Early write or output enable controlled write
Ÿ Max. Active power dissipation
Ÿ Fast access time and cycle time

HY51V64164,HY51V65164
NOTE
1. An initial pause of 200µs is required after power-up followed by 8 /RAS-only refresh cycles before proper device
operation is achieved. In case of using internal refresh counter, a minimum of 8 /CAS- before-/RAS initialization
cycles instead of 8 /RAS-only refresh cycles are required. The device should be carefully initialized to be prevented
from being entered into multi bit parallel test mode during initialization.
2. If /RAS=VSS during power-up, the HY51V64164, HY51V65164 could begin an active cycle. This condition results in
higher current than necessary current which is demanded from the power supply during power-up.
3. It is recommended that /RAS and /CAS track with Vcc during power-up or be held at a valid VIH in order to minimize
the power-up current.
4. V IH(min.) and V IL(max.) are reference levels for measuring timing of input signals. Transition times are measured
between VIH(min.) and VIL(max.), and are assumed to be 5ns for all inputs.
5. Measured at VOH=2.0V and VOL=0.8V with a load equivalent to 1TTL loads and 100pF.
6. tWEZ, tREZ, tCEZ and tOEZ define the time at which the output achieves the open circuit condition and is not referenced
to output voltage levels.
7. Either tRCH or tRRH must be satisfied for a read cycle.
8. These parameters are referenced to /CAS leading edge in early write cycles and to /WE leading edge in read-modifywrite cycles and late write cycle.
9. tWCS, tRWD, tCWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data sheet as
electrical characteristics only. If tWCS ≥ tWCS(min.), the cycle is an early write cycle and data out pin will remain open
circuit (high impedance) through the entire cycle. If tRWD ≥ tRWD(min.), tCWD ≥ tCWD(min.), tAWD ≥ tAWD(min), and tCPWD ≥
tCPWD(min.), the cycle is a read-modify-write cycle and data out will contain data read from the selected cell. If neither
of the above sets of conditions is satisfied, the condition of the data out (at access time) is indeterminate.
10.Operation within the tRCD(max.) limit ensures that tRAC(max.) can be met. tRCD(max.) is specified as a reference point only.
If tRCD is greater than the specified tRCD(max.) limit, then access time is controlled by tCAC.
11.Operation within the tRAD(max.) limit ensures that tRAC(max.) can be met. tRAD(max.) is specified as a reference point only.
If tRAD is greater than the specified tRAD(max.) limit, then access time is controlled by tAA.
12.tREF(max)=128ms is applied to L-parts and SL-parts.
13.A burst of 8192 /RAS-only refresh cycles must be executed within 64ms (128ms for L-parts) after exiting self refresh.
(CBR refresh & Hidden refresh : 4K cycle/64ms)
14.tASC,tCAH are referenced to the earlier /CAS falling edge.
15.tCP is specified from the last /CAS rising edge in the previous to the first /CAS falling edge in the next cycle.
16.tCWD is referenced to the later /CAS falling edge at word read-modifiy-write cycle.
17.tCWL is specified from /WE falling edge to the earlier /CAS rising edge.
18.tCSR is referenced to the earlier /CAS falling before /RAS transition low.
19.tCHR is referenced to the later /CAS rising high after /RAS transition low.
20.tDS is specified for the earlier /CAS falling edge and tDH is specified by the later /CAS falling edge in early write cycle.
