CMOS Synchronous Dynamic RAM
Description
The device is CMOS Synchronous Dynamic RAM organized as 8,388,608 - word x 4 -bit x 4 - bank,
4,194,304 - word x 8 - bit x 4 - bank, or 2,097,152 - word x 16 - bit x 4 - bank. These various organizations
provide wide choice for different applications. It is designed with the state-of-the-art technology to meet stan-
dard PC100 or high speed PC133 requirement. Four internal independent banks greatly increase the perfor-
mance efficiency. It is packaged in JEDEC standard pinout and standard plastic 54-pin TSOP package.
Features
• Single 3.3V ( ±0.3V) power supply
• High speed clock cycle time : 7.5ns/10ns
• Fully synchronous with all signals referenced to a positive clock edge
• Programmable CAS Iatency (2,3)
• Programmable burst length (1,2,4,8,& Full page)
• Programmable wrap sequence (Sequential/Interleave)
• Automatic precharge and controlled precharge
• Auto refresh and self refresh modes
• Quad Internal banks controlled by BA0 & BA1 (Bank select)
• Each Bank can be operated simultaneously and independently
• I/O level : LVTTL compatible
• Random column access in every cycle
• x4, x8, x16 organization
• Input/Output controlled by DQM ( LDQM, UDQM )
• 4,096 refresh cycles/64ms
• Burst termination by burst stop and precharge command
• Burst read/single write option
