3.4 Installing DRAM (SODIMMs)
3.4.1 System Memory
The reverse side of the ROBO-503 contains a socket for 144-pin dual inline memory module
(SODIMM). The socket uses 3.3 V unbuffered synchronous DRAM (SDRAM). SODIMM
module is available in capacities of 32, 64, 128, or 256 MB. The socket can be filled in the
SODIMM of any size, giving your ROBO-503 single board between 32 and 256 MB of
memory.
3.4.2 Supplementary Information About SODIMM
Your ROBO-503 accepts both regular and PC-100 SDRAM SODIMM Module (with or
without parity). Single-sided modules are typically 64 MB; double-sided modules are usually
32 or 128 MB.
3.4.3 Memory Installation Procedures
Press the SODIMM module right down into the socket, until you hear a click. This is when
the two handles have automatically locked the memory module into the correct position of
the SODIMM socket. (See Figure below) To take away the memory module, just push both
handles outward, and the memory module will be ejected by the mechanism in the socket.
