nibble mode DRAM

from The Free On-line Dictionary of Computing (8 July 2008)

Nibble Mode DRAM

   <storage> A standard {DRAM} where four successive {bits} can
   be clocked out of the single data line by successive pulses on
   the CAS\ line while RAS\ is active.  A column address is only
   required for the first bit.

   This mode is now unfashionable but can be found on some older
   64 kilobit and 256 kilobit chips.
