M6Me System Board Manual
enhances system performance be-
cause it provides higher access speed
to the BIOS.
SIMM - An acronym for Standard
Inline Memory Module. A small
printed circuit board containing
memory chips.
Small Computer System Interface
-
See SCSI.
SRAM - An acronym for Static Ran-
dom Access Memory. A type of
memory that can retain data without
requiring a regular clock signal. Al-
though they are faster than DRAM,
they hold less data and are more ex-
pensive.
Synchronous - Protocols that require
the clocks of communicating ma-
chines or devices to be coordinated.
Synchronous Cache - A type of cache
that uses a clock signal to latch the
inputs and the data output. This struc-
ture spreads the cache access across
two or three cycles while maintaining
a bandwidth of one access per cycle.
Improves performance by 5-10%.
Terabyte - A measurement for very
large storage capacity. One Terabyte
is equivalent one-thousand gigabytes,
one-million megabytes, or
1,099,511,627,766 bytes.
VESA - An acronym for Video Elec-
tronics and Standards Association.

VESA Local Bus (VL-Bus)
- A high
performance bus designed by VESA.
A 32-bit version of the ISA bus which
operates at the speed of the
computer’s CPU. See
PCI, EISA and
ISA.
VGA - An acronym for Video Graph-
ics Array. A standard for monitor dis-
plays.
VR - Pentium CPU voltage ranging
from 3.300 - 3.465 Volts.
VRE - Pentium CPU voltage ranging
from 3.400 - 3.600 Volts.
Warm Boot - Restarting the system
by simultaneously pressing the
<Ctrl>, <Alt> and <Delete> keys.
Wide SCSI - A SCSI-2 enhancement
that allows data to be transferred 16
or 32 bits at a time on the SCSI bus
instead of 8 bits at a time.
Write-Back Cache
- Upon a cache
hit, the cache is updated and the main
memory is not affected. Upon a cache
miss, only the main memory is up-
dated.
Write-Through Cache
- Upon a
cache hit, the cache and the main
memory are updated. Upon a cache
miss, only the main memory is up-
dated.
