1,048,576-Word ¥ 1-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM511000C/CL is a 1,048,576-word ¥ 1-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM511000C/CL achieves high integration, high-speed operation, and
low-power consumption because Oki manufactures the device in a quadruple-layer polysilicon/
single-layer metal CMOS process. The MSM511000C/CL is available in a 26/20-pin plastic SOJ or
20-pin plastic ZIP. The MSM511000CL (the low-power version) is specially designed for lowerpower applications.
FEATURES
• 1,048,576-word ¥ 1-bit configuration
• Single 5 V power supply, ±10% tolerance
• Input
: TTL compatible, low input capacitance
• Output : TTL compatible, 3-state
• Refresh : 512 cycles/8 ms, 512 cycles/64 ms (L-version)
• Fast page mode, read modify write capability
• CAS before RAS refresh, hidden refresh, RAS-only refresh capability
• Package options:
26/20-pin 300 mil plastic SOJ (SOJ26/20-P-300-1.27) (Product : MSM511000C/CL-xxJS)
20-pin 400 mil plastic ZIP
(ZIP20-P-400-1.27)
(Product : MSM511000C/CL-xxZS)

Notes:
MSM511000C/CL
1. A start-up delay of 100 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 = 5 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 2 TTL loads and 100 pF.
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. tOFF (Max.) defines the time at which the output achieves the open circuit condition and
is not referenced to output voltage levels.
8. tRCH or tRRH must be satisfied for a read cycle.
9. 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.
10. These parameters are referenced to the CAS leading edge in an early write cycle, and
to the WE leading edge in a read modify write cycle.

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
