1,048,576-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM51V18165B/BSL is a 1,048,576-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM51V18165B/BSL 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 MSM51V18165B/BSL is available in a 42-pin plastic SOJ or
50/44-pin plastic TSOP. The MSM51V18165BSL (the self-refresh version) is specially designed for
lower-power applications.
FEATURES
• 1,048,576-word ¥ 16-bit configuration
• Single 3.3 V power supply, ±0.3 V tolerance
• Input
: LVTTL compatible, low input capacitance
• Output : LVTTL compatible, 3-state
• Refresh : 1024 cycles/16 ms, 1024 cycles/128 ms (SL version)
• Fast page mode with EDO, read modify write capability
• CAS before RAS refresh, hidden refresh, RAS-only refresh capability
• CAS before RAS self-refresh capability (SL version)
• Package options:
42-pin 400 mil plastic SOJ
(SOJ42-P-400-1.27)
(Product : MSM51V18165B/BSL-xxJS)
50/44-pin 400 mil plastic TSOP
(TSOPII50/44-P-400-0.80-K) (Product : MSM51V18165B/BSL-xxTS-K)

Notes:
¡ Semiconductor
1. A start-up delay of 200 µs 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 = 2 ns.
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 100 pF.
The output timing reference levels are VOH = 2.0 V and VOL = 0.8 V.
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 achieves 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.
16. Only SL version.
