DRAM technologies used in SIMMs include FPM (Fast Page Mode memory, used in all 30-pin and early 72-pin modules), and the higher-performance EDO DRAM (used in later 72-pin modules). Due to the differing data bus widths of the memory modules and some processors, sometimes several modules must be installed in identical pairs or in identical ...
All Indigo2 motherboards have 12 SIMM slots, for standard 36-bit parity 72-pin fast page mode SIMM memory modules seated in groups of four. Indigo2 can be expanded to a thermal specification maximum of either 384 MB or 512 MB RAM.

Page mode DRAM was in turn later improved with a small modification which further reduced latency. DRAMs with this improvement are called fast page mode DRAMs (FPM DRAMs). In page mode DRAM, the chip does not capture the column address until CAS is asserted, so column access time (until data out was valid) begins when CAS is asserted.
Later double-data-rate SDRAM standards add additional mode registers, addressed using the bank address pins. For SDR SDRAM, the bank address pins and address lines A10 and above are ignored, but should be zero during a mode register write. The bits are M9 through M0, presented on address lines A9 through A0 during a load mode register cycle.
Using the RamCard's fast page mode 1, 4, 8 or 16 MB SIMM memory modules can be used. [4] External links. The SuperCPU Home (from 2022) with FAQ and software.
The SIMMs are protected by ECC, and the ECC implementation can correct single-bit errors and detect double-bit errors. The SIMMs also contain built-in self-test circuitry, which tests the SIMM during power on or reset and alerts the firmware, which disables the bank(s) of memory containing faulty SIMM(s), if faults are detected.
