摘要： A system that calibrates timing relationships between signals involved in performing write operations is described. This system includes a memory controller which is coupled to a set of memory chips, wherein each memory chip includes a phase detector configured to calibrate a phase relationship between a data-strobe signal and a clock signal received at the memory chip from the memory controller during a write operation. Furthermore, the memory controller is configured to perform one or more write-read-validate operations to calibrate a clock-cycle relationship between the data-strobe signal and the clock signal, wherein the write-read-validate operations involve varying a delay on the data-strobe signal relative to the clock signal by a multiple of a clock period.

摘要： Embodiments of a circuit are described. This circuit includes control logic that generates multiple piecewise-erase commands to erase information stored in a storage cell of a memory device formed within another circuit. Note that execution of a single one of the multiple piecewise-erase commands within the memory device may be insufficient to erase the information stored in the storage cell. Moreover, the first circuit includes an interface that receives the multiple piecewise-erase commands from the control logic and that transmits the multiple piecewise-erase commands to the memory device.

摘要： Systems, among other embodiments, include topologies (data and/or control/address information) between an integrated circuit buffer device (that may be coupled to a master, such as a memory controller) and a plurality of integrated circuit memory devices. For example, data may be provided between the plurality of integrated circuit memory devices and the integrated circuit buffer device using separate segmented (or point-to-point link) signal paths in response to control/address information provided from the integrated circuit buffer device to the plurality of integrated circuit buffer devices using a single fly-by (or bus) signal path. An integrated circuit buffer device enables configurable effective memory organization of the plurality of integrated circuit memory devices. The memory organization represented by the integrated circuit buffer device to a memory controller may be different than the actual memory organization behind or coupled to the integrated circuit buffer device. The buffer device segments and merges the data transferred between the memory controller that expects a particular memory organization and actual memory organization.

摘要： A system that calibrates timing relationships between signals involved in performing write operations is described. This system includes a memory controller which is coupled to a set of memory chips, wherein each memory chip includes a phase detector configured to calibrate a phase relationship between a data-strobe signal and a clock signal received at the memory chip from the memory controller during a write operation. Furthermore, the memory controller is configured to perform one or more write-read-validate operations to calibrate a clock-cycle relationship between the data-strobe signal and the clock signal, wherein the write-read-validate operations involve varying a delay on the data-strobe signal relative to the clock signal by a multiple of a clock period. In a variation of this system, the phase detector on the memory chip is configured to receive signals including a clock signal, a marking signal and a data-strobe signal from the memory controller, wherein the marking signal includes a pulse which marks a specific clock cycle in the clock signal. In this variation, the phase detector is configured to use the marking signal to window the specific clock cycle in the clock signal, and to use the data-strobe signal to capture the windowed clock signal, thereby creating a feedback signal which is returned to the memory controller to facilitate calibration of the timing relationship.
