• 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 stop and precharge
command

organized as 524,288 bits x 32-bit x 4-bank for improved
performance. The synchronous DRAMs achieve high-
speed data transfer using pipeline architecture. All inputs
and outputs signals refer to the rising edge of the clock
input.
