Manufacturer Part Number
k4h1g0738b
Description
Stacked 1gb B-die Ddr Sdram Specification
Manufacturer
Samsung Semiconductor, Inc.
Datasheet
DDR SDRAM stacked 1Gb B-die (x4/x8)
1.0 Key Features
2.0 Ordering Information
3.0 Operating Frequencies
• Double-data-rate architecture; two data transfers per clock cycle
• Bidirectional data strobe
• 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
• 66pin TSOP II
Note : Leaded and Lead-free(Pb-free) can be discriminated by PKG P/N (T : 66 TSOP with Leaded, U : 66 TSOP with Lead-free)
-. Read latency 2, 2.5 (clock)
-. Burst length (2, 4, 8)
-. Burst type (sequential & interleave)
