Revision History
Revision 0.9 (November 11, 2004)
• Corrected typo in boundary scan order table.
Revision 0.8 (October 10, 2004)
• Changed part number from K4J52324QB-G to K4J52324QC-B
-Package code attribute re-defined : G .... 144FBGA, Leaded V .... 144FBGA, Lead-free
A .... 136FBGA, Leaded B .... 136FBGA, Lead-free
Revision 0.7 (October 5, 2004)
• DC spec defined.
• Comment added on how to change the clock frequency after the power-up (page 14)
• Comment added on read to write timing diagram on page 32 which specify the timing interval from data termination enable to the first
data-in should be greater than 1tCK.
• Changed CL(Cas Latency) of -GC14 from 9tCK to 10tCK . Changed CL(Cas Latency) of -GC16 from 8tCK to 9tCK
• Typo corrected in boundary scan order table and additional remark for boundary scan added on page 17.
• Changed tDCERR from 0.2tCK to 0.03tCK (Typo)
Revision 0.6 (September 15, 2004)
• Typo corrected
• Removed tWR_A to avoid confusion. Instead, tWR represent write recovery time for both normal precharge and Auto-precharge cases.
Accordingly tDAL adjusted by tWR for each frequency.
• Clock jitter spec added.
• Changed input capacitance.
• Fixed CL of -GC12 to 11tCK where as specified with 10tCK or 11tCK previousely.
Revision 0.5 (June 4, 2004)
• Typo corrected (Package ball out)
Revision 0.4 (May 13, 2004)
• Changed tRRD from 12ns to 10ns
• Added tFAW specification in the spec which defined as five times of tRRD
• Added boundary scan specification & added package dimension
Revision 0.3 (January 26, 2004)
• Changed part number of 512Mb(x32) GDDR3 from K4J53324QB-GC to K4J52324QB-GC
Revision 0.2 (January 5, 2004)
• Added Write Latency 5, 6, and 7 (clock) in the spec.
• Added tWR_A 8 and 9 (clock) in the spec.
Revision 0.1 (December 18, 2003)
• Changed CL of -GC12 from 9tCK to 10tCK
• Changed tCK(max) from 3.0ns to 3.3ns
Revision 0.0 (December 18 , 2003) - Target Spec
