512K x 32Bits x 2Banks Low Power Synchronous DRAM
Description
These IS42SM/RM/VM32100C are low power 33,554,432 bits CMOS Synchronous DRAM organized as 2 banks of 524,288 words x 32
bits. These products are offering fully synchronous operation and are referenced to a positive edge of the clock. All inputs and outputs
are synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve high bandwidth. All input
and output voltage levels are compatible with LVCMOS.
Features
JEDEC standard 3.3V, 2.5V, 1.8V power supply.
• Auto refresh and self refresh.
• All pins are compatible with LVCMOS interface.
• 4K refresh cycle / 64ms.
• Programmable Burst Length and Burst Type.
- 1, 2, 4, 8 or Full Page for Sequential Burst.
- 4 or 8 for Interleave Burst.
• Programmable CAS Latency : 2,3 clocks.
• Programmable Driver Strength Control
- Full Strength or 1/2, 1/4, 1/8 of Full Strength
• Deep Power Down Mode.
• All inputs and outputs referenced to the positive edge of the
system clock.
• Data mask function by DQM.
• Internal dual banks operation.
• Burst Read Single Write operation.
• Special Function Support.
- PASR(Partial Array Self Refresh)
- Auto TCSR(Temperature Compensated Self Refresh)
• Automatic precharge, includes CONCURRENT Auto Precharge
Mode and controlled Precharge.
