Abstract: A memory system is disclosed that includes memory modules that are longer and taller than conventional prior art memory modules. Each memory module includes two roughly L-shaped openings that extend from the top surface of the memory module near each side surface of the memory module. These L-shaped openings form tabs that extend horizontally along the top surface of the memory module. A guide assembly that includes sockets and guides is adapted to receive the memory module. Rotating latches that couple to each guide near the top of each guide engage a notch on each side surface of the memory module for facilitating insertion and removal. Rotation of each latch into a latched position engages a tab on the memory module so as to securely latch the memory module in place.
