| NEC, ARM to Develop Memory Controller for NEC DRAMs
August 5, 1998 (TOKYO) -- Japan's NEC Corp. and ARM Ltd. of the United
Kingdom said they have agreed to jointly develop a memory controller
for the virtual-channel synchronous dynamic random access memory (DRAM)
developed by NEC.
|ARM supplies many semiconductor microchip makers with microprocessor
cores, called ARM cores, that have been used in mobile phones and personal
The memory controller enables the connection between microchips using
an ARM core and NEC's virtual-channel synchronous DRAMs, which increases
the performance of the system up to 50 percent and decreases power consumption
by about 30 percent, company officials said.
ARM will supply semiconductor microchip makers and electronic design
automation (EDA) vendors which have been licensed to use the ARM cores
with the memory controllers to be developed jointly.
NEC will be able to build up a product supply system through ARM for
the memory controllers that are used for the synchronous DRAMs of its
The virtual-channel synchronous DRAM is a technology to install a channel
between an input-output interface and a memory cell to store data temporary.
It features shorter read/write time than that of conventional DRAMs
that have to read from or write on a memory cell directly. A dedicated
memory controller, however, is needed to spread the use of the virtual-channel
Developments that are similar to those of the virtual-channel synchronous
DRAM are progressing to modify the design architecture of DRAMs.
Fujitsu Ltd.'s FCAM is an example. It also needs a dedicated memory controller.
The alliance between NEC and ARM could be NEC's first move to take the
initiative in the future development of DRAMs.
