Channel  Parallel Processing, Part 2: RAM and HDD  Some Memory
History  Developments in system main memory (also known as RAM -
random access memory) had been mostly linear until AMD and Intel
introduced dual channel controllers in 2003. In the server
space, you can also find Xeon platforms (Bensley or the latest
Stoakley platform for 45 nm processors), which utilize a quad
channel memory controller.  Memory modules, as opposed to
installing individual memory chips, were introduced to
facilitate memory deployment in the 1990s. The first Single
Inline Memory Modules (SIMMs) had 30 pins and were eight bits
wide, which meant that pairs had to be used for 286 and 386SX
computers (16 bit machines), and four SIMMs were required for
386DX systems and up (32 bit architectures). 30-pin SIMM and
SIPP modules were available at 256 kB to 4 MB each, and they
were replaced by the 72-pin PS/2 SIMMs in the mid ’90s. The fact
that at least two or four modules ha
