Abstract: Memory controllers, devices, modules, systems and associated methods are disclosed. In one embodiment, a memory controller is disclosed. The memory controller includes write queue logic that has first storage to temporarily store signal components of a write operation. The signal components include an address and write data. A transfer interface issues the signal components of the write operation to a bank of a storage class memory (SCM) device and generates a time value. The time value represents a minimum time interval after which a subsequent write operation can be issued to the bank. The write queue logic includes an issue queue to store the address and the time value for a duration corresponding to the time value.

Abstract: A memory component internally generates and stores the check bits of error detect and correct code (EDC). In a first mode, during a read transaction, the check bits are sent to the memory controller along with the data on the data mask (DM) signal lines. In a second mode, an unmasked write transaction is defined where the check bits are sent to the memory component on the data mask signal lines. In a third mode, a masked write transaction is defined where at least a portion of the check bits are sent from the memory controller on the data signal lines coincident with an asserted data mask signal line. By sending the check bits along with the data, the EDC code can be used to detect and correct errors that occur between the memory component and the memory controller.

Abstract: A memory device is disclosed that includes a row of storage locations that form plural columns. The plural columns include data columns to store data and a tag column to store tag information associated with error locations in the data columns. Each data column is associated with an error correction location including an error code bit location. Logic retrieves and stores the tag information associated with the row in response to activation of the row. A bit error in an accessed data column is repaired by a spare bit location based on the tag information.

Abstract: The present embodiments provide a system that supports self-refreshing operations in a memory device. During operation, the system transitions the memory device from an auto-refresh state, wherein a memory controller controls refreshing operations for the memory device, to a self-refresh state, wherein the memory device controls the refreshing operations. While the memory device is in the self-refresh state, the system sends progress information for the refreshing operations from the memory device to the memory controller. Next, upon returning from the self-refresh state to the auto-refresh state, the system uses the progress information received from the memory device to control the sequencing of subsequent operations by the memory controller.

The kit may include a second component that includes a second plurality of pairs of opposing tabs configured to maintain a second subassembly component at a second fixed position relative to the first component. The first subassembly component may be configured to couple to the second subassembly component to maintain an optical fiber in a fixed rotational position relative to the first subassembly component and the second subassembly component.

Abstract: A phasemeter for estimating the phase of a signal. For multi-tone signals, multiple phase estimates may be provided. An embodiment includes components operating in the digital domain, where a sampled input signal is multiplied by cosine and sine terms to provide estimates of the inphase and quadrature components. The quadrature component provides an error signal that is provided to a feedback loop, the feedback loop providing a model phase that tends to track the phase of a tone in the input signal. The cosine and sine terms are generated from the model phase. The inphase and quadrature components are used to form a residual phase, which is added to the model phase to provide an estimate of the phase of the input signal. Other embodiments are described and claimed.
