RAMBUS HAS SPECS FOR MOBILE VERSION OF DIRECT MEMORY.
Rambus Inc has now issued the specifications for Direct RDRAM (Rambus DRAM) Pronounced "r-d-ram." A dynamic RAM chip technology from Rambus, Inc., Los Altos, CA (www.rambus.com). Rambus licensed its memory designs to semiconductor companies, which manufactured the chips. memory technology suitable for mobile devices, including Rambus memory
devices and SO-RIMM small outline memory modules and connectors, so
that laptops can take advantage of the two-times memory bandwidth Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of the commonly used increase over current SDRAMs without using up too much space or taking
up too much power. Mobile systems will support 16Mb to 384Mb using 128
megabit RDRAMs, with module upgrade plans for future 256 megabit and
512 megabit RDRAM densities. Up to three modules can be supported.
Power consumption should be half the power of comparable SDRAM (Synchronous DRAM) A type of dynamic RAM (DRAM) memory chip that has been widely used since the late 1990s. SDRAM chips eliminated wait states by dividing the chip into two cell blocks and interleaving data between them. ,
depending on the workload. Toshiba America Electronic Components Inc and
Kingston Technology Kingston Technology Co. is an American producer of memory products. It is located in Fountain Valley, California with manufacturing and logistics facilities in the United States, United Kingdom, Ireland, Malaysia, China and Taiwan. Co have been working with Rambus on the RIMM (Rambus Inline Memory Module) See RDRAM. See also RIM. and
SO-RIMM memory modules for RDRAM, and delivered the first 160-pin
module prototypes to Rambus for mobile systems, initially using 72
megabit RDRAMs. Smart Modular Technologies Inc also has sample modules
available, and Molex Inc says it will have samples this quarter. Intel
Corp charts show that it expects the take-up of Direct RDRAM in mobile
systems to begin in the middle of next year.
