DRAM

In DRAM access, what is the operation called that closes the open row and returns the bit lines to an intermediate voltage to prepare for activating the next row?

  1. ARefresh
  2. BPrecharge
  3. CErase
Show answer and explanation

Answer: B. Precharge

Before accessing a different row, DRAM must precharge: close the current row and return the bit lines to an intermediate voltage. This time is included in access latency, so its impact is reduced by increasing consecutive accesses to the same row and by using multiple banks.
