DRAM Timing Conguration

Primary Timing

CAS# Latency (tCL)

e time between sending a column address to the memory and the beginning of the data

in response.

RAS# to CAS# Delay to Read (tRCDRD)

RAS# to CAS# Delay : e number of clock cycles required between the opening of

a row of memory and accessing columns within it.

e number of clock cycles required between the opening of a row of memory and

accessing columns within it

RAS# to CAS# Delay to Write (tRCDWR)

RAS# to CAS# Delay : e number of clock cycles required between the opening of a row

of memory and accessing columns within it.

e number of clock cycles required between the opening of a row of memory and

accessing columns within it.

Row Precharge Time (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

precharge command.

Secondary Timing

Fail Count

e number of training failure/retries required before boot from recovery mode.
