NEC heeft bekend gemaakt dat het van Rambus Inc. als eerste DRAM bakker goedkeuring heeft verkregen voor een 288Mbit Rambus chip met ECC foutcorrectie. De chips kunnen in aantallen van 4-16 gecombineerd worden tot een reepje van 144 tot 576MB. Engineering samples komen waarschijnlijk in juli beschikbaar:
NEC Corporation (NEC) and NEC Electronics Inc. have received the first validation issued by Rambus Inc. for a 288 Mb (megabit) Direct Rambus® DRAM (RDRAM) device. The validation was awarded to NEC's uPD488588 288 Mb direct RDRAM product and can be viewed at www.rambus.com/developer/validation_rdram_results.html.
Validation for NEC's 288 Mb Direct RDRAM device represents an important step toward rapidly meeting increasing customer demand for high-density, high-performance Rambus memory with error correction capability (ECC) for applications in the high-performance PC workstation and PC server arenas.
NEC's 18-bit data path 288 Mb uPD488588 provides ECC and interleaved device mode (IDM) functions, and is available in Rambus inline memory modules (RIMM(TM)) that mount 4-16 devices in densities ranging from 144 MB to 576 MB.
The device utilizes a tape FBGA (uBGA) package as used with the 128 Mb RDRAM that is now in volume production. With 512K word x 18-bit x 32-bank organization, the device provides 4-bank interleave operation, enabling banks to be switched -- even during processing -- and achieving a maximum data transfer rate of 1.6 GB (gigabytes) per second at a data transfer frequency of 400 MHz. Each bank provides a page size of 2 KB.
Pricing and Availability
The validation by Rambus puts NEC on schedule to have engineering samples by the end of July and customer samples by mid August. Mass production will closely follow. Please contact your local NEC representatives for current pricing information. Pricing and availability are subject to change.
