Nanya (NT) - SDRAM

How do I read the type number?

NT5SV16M16AT-8B
^^------------------- NT = Nanya
NT5SV16M16AT-8B
   ^----------------- 5 = Memory?
NT5SV16M16AT-8B
   ^^---------------- SV = 3.3 volt / SDRAM
                      DS = 2.5 volt / DDR SDRAM
NT5SV16M16AT-8B
     ^^^^^----------- 16M16 = 4 Banks x 4M x 16 (256Mbit) : check module size/banks
                      32M8  = 4 Banks x 8M x 8  (256Mbit) : check module size/banks
NT5SV16M16AT-8B
             ^^------ Speed:
                      8B  = DDR200  / PC100
                      75B = DDR266B / PC133
                      7K  = DDR266A / PC133
                      6   = DDR333
                      6K  = DDR333  / PC166
                      5   = DDR400A
