DDR3-4Gb E-Die
NT5CB(C)512M8EQ/NT5CB(C)256M16ER
NOTE 1 Please refer to ordering information for the detail.
NOTE 2 1.35V DDR3L are backward compatible to 1.5V DDR3 parts. Please refer to page 5 operating frequency table
NOTE 3 If T
C
exceeds 85°C, the DRAM must be refreshed externally at 2x refresh, which is a 3.9us interval refresh rate. Extended SRT or ASR must be enabled.
NOTE 4 Violating tRFC specification will induce malfunction.
NOTE 5 Only Support prime DQ’s feedback for each byte lane.
