Hex = multiples of 16: {...4096, 256, 16, 1} so AA0 = 2720 (10*256+10*16+0*1)
Binary = multiples of 2: {...16, 8, 4, 2, 1} so 10101 = 21 (16+0+4+0+1)

RAM - Random Access Memory
SRAM (static) Usually L2 Cache - fast and expensive, 256k max chip, 10ns.
DRAM (dynamic) Main system memory - slower but cheaper, many Mb per chip, 60-90ns:
EDO - Extended Data Out, 60ns
SDRAM - Synchronous Dynamic, 100-133MHz, twice as fast as EDO
RDRAM - Rambus Dynamic, 800MHz-1.6GHz
fast-paged RAM (rare)
SDLRAM (rare)
BEDO (rare)
VRAM (video) video adapter RAM only:
WRAM - Window, faster than original VRAM, retrieves larger data blocks
Memory Modules - small, removeable circuit board that holds the RAM chips:
DIP - Dual Inline Package, inserted directly into the motherboard, suffers "chip creep"
SIMM - Single Inline Memory Module, 30-pin=8bit, 72-pin=32bit, fast-page or EDO chips
DIMM - Dual Inline Memory Module, 168-pin 64-bit, EDO or SDRAM
RIMM - Rambus Inline Memory Module, 184-pin 16-bit, proprietary.
Memory bank = number of memory modules needed to match a processor's bus width.
Example: A 64-bit processor needs 1 DIMM(64bit), 2 SIMM(2x32bit), or 4 RIMMs (4x16bit).
