Page Mode Dynamic Random Access Memory

Page Mode Dynamic Random Access Memory
Page Mode DRAM

   <hardware, storage> A technique used to support faster
   sequential access to {DRAM} by allowing any number of accesses
   to the currently open row to be made after supplying the {row
   address} just once.

   The {RAS} signal is kept active, and with each {falling edge}
   of the {CAS}\ signal a new {column address} can be supplied
   and the corresponding bits can be accessed.  This is faster
   than a full RAS-CAS cycle because only the shorter Column
   Access Time needs to be obeyed.

   Note that strictly speaking such a DRAM is not a true {random
   access memory} since accesses to the open row are faster than
   to other locations.

   {EDO RAM} is replacing Page Mode DRAM in many new
   microcomputers.

   [Is "Fast Page Mode" the same as "Page Mode"?]
