SIMM
Shown here is an example of a SIMM RAM chip.
One drawback of DIP technology was the large amount of space the memory
took up on the motherboard. SIMM or Single Inline memory Module, seen in
computers even today, was developed to overcome this problem. SIMM chips
are simply a circuit board with a row of attached DIPs. Then, in order
to connect them to the motherboard and keep them easily removable a new
slot design was introduced. Therefore, the SIMM chips are connected to
the computer through slots at 45-degree angles. One drawback to the SIMM
chip was the observed "chip creep" to the chips. Chip creep is when the
chips seem to move out of the slots over time, due to continual heating
and cooling.
Note: When installing the SIMM chips to work
with a 64-bit processor make sure you pair them together. Otherwise, if
you are installing them with a 32-bit processor you only need to install
one.
