ABSTRACT:
A memory system that includes switches for controlling data transfer that are disposed on the motherboard. The switches are selectively coupled to a controller and to connector receptacles that are adapted to receive a memory module. The memory system also includes resistors that are disposed on the motherboard for terminating data signals. In one embodiment, memory modules are accessed in pairs. That is, the data switches are used to control the flow of data signals such that data signals only flow to one pair of memory modules at any particular time. In one embodiment, the memory system of the present invention includes eight memory modules that use DDR SDRAM memory components. When 8 Mbit, 16 Mbit, 32 Mbit or 64 Mbit memory components are used, this configuration gives a range of memory configurations from 128 megabytes (Mbytes) to 1 gigabyte (Gbyte).
