VG36644041DT / VG36648041DT / VG36641641DT
CMOS Synchronous Dynamic RAM
Description
The VG36644041D, VG36648041D and VG36641641D are high-speed 67,108,864-bit synchronous
dynamic random-access memories, organized as 4,194,304 x 4 x 4, 2,097,152 x 8 x 4 and 1,048,576 x 16 x
4 (word x bit x bank), respectively.
The synchronous DRAMs achieved high-speed data transfer using the pipeline architecture. All input
and outputs are synchronized with the positive edge of the clock.The synchronous DRAMs are compatible
with Low Voltage TTL (LVTTL).These products are packaged in 54-pin TSOPII.
Features
Single 3.3V (
) power supply
High speed clock cycle time
-6 : 166MHz<3-3-3>, available only on 4MX16 option
-7 : 143MHz<3-3-3>, 133MHz<2-3-2>
-7L: 133MHz<3-3-3>
-8H: 100MHz<2-2-2>
Fully synchronous operation referenced to clock rising edge
Possible to assert random column access in every cycle
Quad internal banks controlled by A12 & A13 (Bank Select)
Byte control by LDQM and UDQM for VG36641641D
Programmable Wrap sequence (Sequential / Interleave)
Programmable burst length (1, 2, 4, 8 and full page)
Programmable /CAS latency (2 and 3)
Automatic precharge and controlled precharge
CBR (Auto) refresh and self refresh
X4, X8, X16 organization
LVTTL compatible inputs and outputs
