Functional Description

One write data mask input (DM) for
×
4 and
×
8
components and two write data mask inputs (LDM,
UDM) for
×
16 components are supported on DDR2
SDRAM’s, consistent with the implementation on DDR
SDRAM’s. It has identical timings on write operations
as the data bits, and though used in a uni-directional
manner, is internally loaded identically to data bits to
Write Data Mask
insure matched system timing. Data mask is not used
during read cycles. If DM is HIGH during a write burst
coincident with the write data, the write data bit is not
written to the memory. For
×
8 components the DM
function is disabled, when RDQS / RDQS are enabled
by EMRS(1).
