2.12 System Memory DRAM
The HS-4500 provides a wide range on-board DRAM memory by two
pieces SIMM sockets (Bank0 & Bank1) to accept 1 MB, 2MB, 4MB, 8MB,
16MB, 32MB or 64MB. The SIMMs (Single In-Line Memory Modules)
RAM request the access time should be 70 n-second or faster. The total
capacities of the on board SIMM’s memory are between 2MB to 128MB.
With one additional DIMM socket of maximum 256MB-memory capacity,
the total memory size may up to 384MB on board.
See the figure on section 2.3 for get the identifying the banks. Please
take notes that the memory capacity of both SIMMs should be the same.
