IS42VS16400L - 1 Meg Bits x 16 Bits x 4 Banks (64-MBIT) SYNCHRONOUS DYNAMIC RAM

The 64Mb SDRAM is a high speed CMOS, dynamic random-access memory designed to operate in 1.8V 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 4,096 rows by 256 columns by 16 bits.

• Clock frequency: 133 MHz.
• Fully synchronous; all signals referenced to a positive clock edge.
• Internal bank for hiding row access/precharge.
• Single 1.8V power supply.
• LVTTL interface.
• Programmable burst length.
• (1, 2, 4, 8, full page).
• Programmable burst sequence: Sequential/Interleave.
• Self refresh modes.
• Auto refresh (CBR).
• 4096 refresh cycles every 64 ms (Com, Ind, A1 grade) or 16.
