128 M-bit Direct Rambus DRAM

Description

The Direct Rambus DRAM (Direct RDRAM ) is a general purpose high-performance memory device suitable for

use in a broad range of applications including computer memory, graphics, video, and any other application where

high bandwidth and low latency are required.

The PD488448 is 128M-bit Direct Rambus DRAM (RDRAM ), organized as 8M words by 16 bits.

The use of Rambus Signaling Level (RSL) technology permits 600 MHz to 800 MHz transfer rates while using

conventional system and board design technologies. Direct RDRAM devices are capable of sustained data transfers

at 1.25 ns per two bytes (10 ns per sixteen bytes).

The architecture of the Direct RDRAMs allows the highest sustained bandwidth for multiple, simultaneous randomly

addressed memory transactions. The separate control and data buses with independent row and column control

yield over 95% bus efficiency. The Direct RDRAM’s thirty-two banks support up to four simultaneous transactions.

System oriented features for mobile, graphics and large memory systems include power management, byte

masking.

The PD488448 is offered in a CSP horizontal package suitable for desktop as well as low-profile add-in card and

mobile applications. Direct RDRAMs operate from a 2.5 volt supply.

Features

Highest sustained bandwidth per DRAM device

•

- 1.6 GB/s sustained data transfer rate

- Separate control and data buses for maximized efficiency

- Separate row and column control buses for easy scheduling and highest performance

- 32 banks: four transactions can take place simultaneously at full bandwidth data rates

Low latency features

•

- Write buffer to reduce read latency

- 3 precharge mechanisms for controller flexibility

- Interleaved transactions

Advanced power management:

•

- Multiple low power states allows flexibility in power consumption versus time to transition to active state

- Power-down self-refresh

Overdrive current mode

•

Organization: 1 Kbyte pages and 32 banks, x 16

Uses Rambus Signaling Level (RSL) for up to 800 MHz operation

Package : 62-pin TAPE FBGA ( BGA ) and 62-pin PLASTIC FBGA (D²BGA (Die Dimension Ball Grid Array) )
