small circuit board
s carrying memory {integrated circuit
s}, with
signal and power pin
s on both
side
s of the board, in contra
st to
single-in-line memory modules (
sIMM). The individual gold or lead connector
s (pin
s) on
sIMM
s, although they are on both
side
s of the chip, are connected to the
same memory chip, while on a DIMM, the connection
s on each
side of the module connect to different chip
s. Thi
s allow
s for a wider data path, a
s more module
s can be acce
ssed at once. DIMM pin
s are arranged in a zigzag de
sign to allow PCB track
s to pa
ss between them. The 8-byte DIMM format with dual-
sided contact
s can accommodate 4- and 16-megabit
dynamic RAM chip
s, and i
s predicted to handle 64- and 256-Mbit device
s. The 8-byte DIMM will hold up to 32 megabyte
s of memory u
sing 16-Mbit DRAM
s, but with the 256-Mbit future-generation DRAM, it will be able to hold a 64-Mx64 configuration. Another variation, the 72-pin
sO-DIMM, i
s de
signed to connect directly to 32 bit data bu
se
s, and i
s intended for u
se in memory-expan
sion application
s in
notebook computers. A Dual in-line memory module (DIMM), a
s oppo
sed to
sIMM
s (u
sed by the majority of the PC indu
stry) allow
s for a 128-bit data path by interleaving memory on alternating memory acce
ss cycle
s.
sIMM
s on the other hand, have a 64-bit data path.
supplier
s are unanimou
s in their belief that the DIMM will eventually replace the
sIMM a
s the market'
s preferred memory module. (1996-01-28)
