MEMORY SYSTEM
Panther-II supports the use of 256K, 1M and 4M DRAMs
device configurations for up to 16MB of on-board system memory.
Both page mode and interleave operation are incorporated on
the system board DRAM. Page mode is enabled or disabled for each
pair of DRAM banks independently. When on, it is active on all
memory maps for the enabled bank pairs. Interleaving requires pairs of
banks. Both page mode and interleave are automatically enabled. One
bank of memory refers to as 2 modules of SIMM or 4 pieces of DIP
DRAM. Detailed operation of each is given in the following sections.
Interleave Operation
Two-way interleaving is automatically enabled whenever both
memory banks of a pair are populated with same DRAM types. If all
four banks are populated with same DRAMs, four-way interleaving
automatically occurs. If the four memory banks are not populated with
same DRAMs, two-way interleaving occurs on pairs that are of the same
type.
In a system with three banks populated, the first two banks
perform two-way interleave if they are of the same DRAM type. Next
table shows the automatic interleaving options that occur versus the
number of populated banks. In the table, Bank 0,1,2 and 3 are the
designations for each of the four DRAM banks. In the columns below
these designators, "Yes" or "No", indicate whether the bank is
populated.
