in response.
RAS# to CAS# Delay (tRCD)
e number of clock cycles required between the opening of a row of memory and
accessing columns within it.
Row Precharge (tRP)
e number of clock cycles required between the issuing of the precharge command and
opening the next row.
RAS# Active Time (tRAS)
e number of clock cycles required between a bank active command and issuing the
