L1
Cache
Level 1 cache. A small cache integrated
in a processor that provides quick
access to the most recently used
data.
L2
Cache
Level 2 cache. L2 cache has the
same purpose as L1 cache, but
is usually not integrated into
the processor. L2 cache is traditionally
made of SRAM and in socket 7 and
older motherboards was in some
cases upgradeable. See COAST.
Latency
(also called CAS Latency)
The amount of time in nanoseconds
(often measured in clock cycles)
between a request to read the
memory, and when it is actually
output. SDRAMs are typically referred
to as CL2 or CL3, with CL2 parts
being faster.
Lead
The official name for the metal
"feet" on an IC. Also called "pins."
The part of the lead assembly
that is formed after a portion
of the lead frame is cut away.
The chip's connection to the outside
world.
