Abstract:
An apparatus, system, and method are disclosed for caching fully buffered memory (FBM) data. A circuit card is connected to an FBM socket that is configured to receive a FBM. An interface module communicates with a memory controller and at least one FBM via the FBM socket through a plurality of electrical interfaces. A cache controller apportions memory space in the cache memory between each FBM of the at least one FBM according to an apportionment policy. A cache memory transparently stores data from the at least one FBM and the memory controller and transparently provides the data to the memory controller. The cache controller manages coherency between the at least one FBM and the cache memory.
Abstract:
Method and systems are disclosed for increasing the number of ranks supported in a memory system. In one embodiment, a plurality of predefined subsets of memory chips on a memory module is selected. A chip select signal uniquely identifying the selected subset of memory chips is generated. The chip select signal is encoded as a multi-bit word having a bit width that is less than the number of predefined subsets of memory chips. Each bit of the encoded chip select signal is transmitted along a separate chip select line. The transmitted chip select signal is decoded to determine the identity of the selected subset of memory chips. The selected subset of memory chips identified by the decoded chip select signal are read or written.

Abstract:
Memory systems and methods of forming memory modules. In one embodiment, a computer memory system includes a substantially tubular frame with an elongate card edge extending along the frame. A flexible circuit comprising a flexible substrate, a plurality of memory chips affixed to the flexible substrate, and a plurality of electrical terminals interconnected with the memory chips, is secured along a perimeter of the tubular frame with the electrical terminals arranged along the card edge.
Abstract:
Method and apparatus for installing a processor into electronic communication with a socket. The land grid array socket connector includes a socket housing secured to a circuit board and an array of upwardly extending pins for electronic communication with contact pads on the processor. The socket connector provides a carriage configured to receiving the processor through a lateral opening and support a perimeter edge of the processor. A mechanical linkage couples the carriage and the socket housing for substantially vertically translating the processor relative to the socket. A plurality of alignment features upwardly extends from the socket housing along the perimeter of the array of pins. Each of the alignment features has an inwardly-facing tapered surface for registering the edge of the processor and biasing the processor into a position where the array of contact pads are aligned with the array of pins as the processor is lowered.
