20100050010Data-Width Translation Between Variable-Width and Fixed-Width Data Ports - Described are memory modules that support dynamic point-to-point extensibility using fixed-width memory die. The memory modules include data-width translators that allow the modules to vary the effective width of their external memory interfaces without varying the width of the internal memory interfaces extending between the translators and associated fixed-width dies. The data-width translators use a data-mask signal to selectively prevent memory accesses to subsets of physical addresses. This data masking divides the physical address locations into two or more temporal subsets of the physical address locations, effectively increasing the number of uniquely addressable locations in a given module. Reading temporal addresses in write order can introduce undesirable read latency. Some embodiments reorder read data to reduce this latency.02-25-2010

The phase interpolator has an output that provides the output clock signal (Q_CLKn, Q_NCLKn) to the memory modules through a flip-flop (FF1 DELAY) and output driver matched with the flip-flop and output driver of the data paths. A phase frequency detector (PFD) has a first input (REF) coupled to the output of the output driver replica and a second input (SYS) coupled to the clock output. The phase interpolator is controlled by the output of the phase frequency detector (PFD). The proposed data register satisfies the three requirements of: (i) setup and hold timing on the pre-register side, (ii) clock centering on the post-register side, and (iii) constant propagation delay time (tpd) over PVT variations from the clock input to the data output.12-04-2008
