• Manufacturer Part Number: K4H560438E-GCC4
• Description: 256Mb E-die DDR 400 SDRAM Specification 60Ball FBGA (x4/x8)
• Manufacturer: SAMSUNG [Samsung semiconductor]

DDR SDRAM 256Mb E-die (x4, x8)
*CL : CAS Latency
Key Features
• 200MHz Clock, 400Mbps data rate.
• VDD= +2.6V + 0.10V, VDDQ= +2.6V + 0.10V
• Double-data-rate architecture; two data transfers per clock cycle
• Bidirectional data strobe [DQ] (x4,x8)
• Four banks operation
• Differential clock inputs(CK and CK)
• DLL aligns DQ and DQS transition with CK transition
• MRS cycle with address key programs
• All inputs except data & DM are sampled at the positive going edge of the system clock(CK)
• Data I/O transactions on both edges of data strobe
• Edge aligned data output, center aligned data input
• DM for write masking only (x4, x8)
• Auto & Self refresh
• 7.8us refresh interval(8K/64ms refresh)
• Maximum burst refresh cycle : 8
• 60Ball FBGA package
