General Description:

The 128Mb SDRAM is a high-speed CMOS, dynamic random-access memory containing 134,217,728 bits. Each is internally configured as a quad-bank DRAM. Read and write accesses to the SDRAM are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence.

Features:

• Intel PC-100 (3-3-3) or PC133 (3-3-3) compatible

• Fully synchronous; all signals registered on positive edge of system clock

• Internal pipelined operation; column address can be changed every clock cycle

• Internal banks for hiding row access precharge time

• Programmable burst lengths: 1, 2, or 4 using Interleaved Burst Addressing

• Auto Precharge and Auto Refresh modes

• 64ms, 4,096-cycle refresh quad-row refresh, (15.6ms/row)

• Self Refresh mode 1

• LVTTL-compatible inputs and outputs

• Single +3.3V ±0.3V power supply

• The x16 devices are optimized for both single and dual rank DIMM applications. The x8 devices are optimized for single rank DIMM applications.
