The 64Mb SDRAM is a high speed CMOS, dynamic random-access memory designed to operate in 3.3V memory systems containing 67,108,864 bits. Internally configured as a quad-bank DRAM with a synchronous interface. Each 16,777,216-bit bank is organized as 2,048 rows by 256 columns by 32 bits. The 64Mb SDRAM includes an AUTO REFRESH MODE, and a power-saving, power-.
• Clock frequency: 200, 166, 143, 133 MHz
• Fully synchronous; all signals referenced to a
positive clock edge
• Internal bank for hiding row access/precharge
• Single 3.3V power supply
• LVTTL interface
• Programmable burst length:
(1, 2, 4, 8, full page)
• Programmable burst sequence:
Sequential/Interleave
• Self refresh modes
• 4096 refresh cycles every 16ms (A2 grade) or
64ms (Commercia, Industrial, A1 grade)
• Random column address every clock cycle
• Programmable CAS latency (2, 3 clocks)
• Burst read/write and burst read/single write
operations capability
• Burst termination by burst st.
