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.

Semiconductor Notes:
MSM511000C/CL
1. A start-up delay of 100 s 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).
