Memory Configuration
Memory Configuration
Banks and
Slots A bank represents the eight memory arrays (SIMMs 0 through
7) as shown in Figure 2–4. A slot consists of two banks because
every memory array can be populated on both sides as shown.
Example The following example shows a sample memory mother board
configuration and the relationship between banks, SIMM
memory size, and slots. For the DEC 3000 Model 600/600S AXP
system, the banks are numbered 0 through 3.

Banks Meaning
0 and 1 Occupy slot 1. Banks 0 and 1 are
two-sided SIMMs that consist of 64 MB.
2 and 3 Occupy slot 2. Banks 2 and 3 are
single-sided SIMMs that consist of 32
MB.
Two banks occupy one memory slot. Each memory card (SIMM)
can be populated on both sides, which total 64 MB per SIMM
card maximum (32 MB on each side). This is not the case with
the 16 MB and 32 MB SIMMs.
