System Memory Configuration
The TouchStar system memory can be configured with up to
64MB of dynamic random access memory (DRAM). The DRAM
is implemented in two 3.3 Volt SODIMMs (small outline dual-
in-line memory modules) that plug into sockets on the
motherboard. Each SODIMM socket can hold either a SODIMM
containing 4, 8, or 16 MB. All system memory above 1MB is
accessible as extended memory. Table 9 illustrates some possible
DRAM combinations installed in the two SODIMM sockets.
SODIMMs differ in physical dimensions; please refer to Figure
18 for the required outline dimensions and component clear-
ances on SODIMMs used in the TouchStar system.
