4,194,304-Word × 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MD51V65165E is a 4,194,304-word × 16-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS
technology. The MD51V65165E achieves high integration, high-speed operation, and low-power
consumption because Oki manufactures the device in a quadruple-layer polysilicon/double-layer metal
CMOS process. The MD51V65165E is available in a 50-pin plastic TSOP.
FEATURES
· 4,194,304-word × 16-bit configuration
· Single 3.3V power supply, ±0.3V tolerance
· Input : LVTTL compatible, low input capacitance
· Output : LVTTL compatible, 3-state
· Refresh :
RAS only refresh
: 4096 cycles/64ms
CAS before RAS refresh, hidden refresh
: 4096 cycles/64ms
· Fast page mode with EDO, read modify write capability
· CAS before RAS refresh, hidden refresh, RAS-only refresh capability
· Packages

Notes: 1. A start-up delay of 200µs is required after power-up, followed by a minimum of eight initialization
cycles (RAS-only refresh or CAS before RAS refresh) before proper device operation is achieved.
2. The AC characteristics assume tT = 2ns.
3. VIH (Min.) and VIL (Max.) are reference levels for measuring input timing signals. Transition times (tT)
are measured between VIH and VIL.
4. This parameter is measured with a load circuit equivalent to 1 TTL load and 100pF.
The output timing reference levels are VOH=2.0 and VOL=0.8V.
5. 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 the access time is controlled by tCAC.
6. 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 the access time is controlled by tAA.
7. tCEZ (Max.), tREZ (Max.), tWEZ (Max.), and tOEZ (Max.) define the time at which the output achieved the
open circuit condition and are not referenced to output voltage levels.
8. tCEZ, and tREZ must be satisfied for open circuit condition.
9. tRCH or tRRH must be satisfied for a read cycle.
10. tWCS, tCWD, tRWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data
sheet as electrical characteristics only. If tWCS ≥ tWCS (Min.), then the cycle is an early write cycle and
the data out will remain open circuit (high impedance) throughout the entire cycle. If tCWD ≥ tCWD
(Min.), tRWD ≥ tRWD(Min.), tAWD ≥ tAWD (Min.) and tCPWD ≥ tCPWD (Min.), then 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, then the condition of the data out (at access time) is indeterminate.
11. These parameters are referenced to the UCAS and LCAS, leading edges in an early write cycle, and to
the WE leading edge in an OE control write cycle, or a read modify write cycle.
12. These parameters are determined by the falling edge of either UCAS or LCAS, whichever is earlier.
13. These parameters are determined by the rising edge of either UCAS or LCAS, whichever is later.
14. tCWL should be satisfied by both UCAS and LCAS.
15. tCP is determined by the time both UCAS and LCAS are high.
