1M x 4 BANKS x 16 BITS SDRAM
May., 2003
64Mb SDRAM
■ 3.3 volt 4Mx16
■ 125/133/143/166/183/200 MHz SDRAM
■ 4 banks, 4K refresh
GENERAL DESCRIPTION
The VT3664164T is a high-speed synchronous dynamic random access memory (SDRAM),
organized as 1M words x 4 banks x 16 bits. Using pipelined architecture technology. Accesses
www.DataShtoeett4hUe.coSmDRAM are burst oriented. Consecutive memory location in one page can be accessed
at a burst length of 1,2,4,8 or full page when a bank and row is selected by an ACTIVE
command. By having a programmable Mode Register, the system can change burst length,
latency cycle, interleave or sequential burst to maximize its performance.
FEATURES
■ 3.3V ± 0.3V power supply
■ 1,048,576 words x 4 banks x 16 bits organization
■ Four banks operation
■ Power-down Mode
■ Sequential and interleave burst
■ Burst Length: 1,2,4,8 and full page
■ CAS latency: 2 and 3
■ 4K refresh cycles/64 ms
■ Auto & self refresh
■ DQM for masking
■ Burst read single-bit write operation
■ LVTTL compatible with multiplexed address
■ All inputs are sample at the positive going edge of the system clock
■ Reflow temperature condition: Max 245℃~250℃
■ The environmental testing temperature：
All type of VT SDRAM testing temperature at 75℃(Max).
