Subsystem The memory subsystem includes the following:
Four memory motherboards (MMB) that mount on the system
module. To have an operational memory subsystem, all four
MMBs must be present.
The memory arrays are spread among the four MMBs. Each
bank of memory consists of eight memory modules, two on
each MMB.
The memory subsystem can support up to 256M bytes, with a
future expansion of up to 1 gigabyte of memory.
