International Classification:

G06F 1/00

US Classification:

713320, 713300

Abstract:

A method for managing a memory controller comprising selecting a low-power state from a plurality of low-power states. The method further comprises transitioning to the low-power and entering the low-power state when the transition is complete, provided a wake-event has not been received. An apparatus comprises a controller configured to select a power state for transition, a state-machine configured to execute steps for transitions between power states of a memory controller connected by a bus to a memory, a storage configured to store at least one context, and a context engine configured to stream, at the direction of the state-machine engine, the at least one context to the memory controller. Streaming comprises communicating N portions of context data as a stream to N registers in the memory controller. A context comprises a plurality of calibrations corresponding to a state selected for transition.

International Classification:

G06F 13/372

US Classification:

710117

Abstract:

A method including sorting read/write commands initiated by a memory controller based upon a destination page within a memory device. The read/write commands having a highest priority level are determined. The commands are then categorized as either page movement commands or data movement commands. The page movement commands or data movement commands are sent to the memory device based upon a signal indicating a current direction of a data bus providing communication between the memory controller and the memory device and further based upon a priority level.

International Classification:

G11C 11/56

US Classification:

711105

Abstract:

A method of training chip select for a memory module. The method includes programming a memory controller into a mode wherein a command signal is active for a programmable time period. The method then programs a programmable delay line of the chip select with a delay value and performs initialization of the memory module. The memory module is then placed in a write leveling mode wherein placing the memory module in the write leveling mode toggles a state of the chip select. A write leveling procedure is then performed and a response thereto is determined from the memory module. A determination is made whether the memory module is in a pass state or an error state based on the response.

Abstract:

A method of training chip select for a memory module. The method includes programming a memory controller into a mode wherein a command signal is active for a programmable time period. The method then programs a programmable delay line of the chip select with a delay value and performs initialization of the memory module. A read command is then sent to the memory module to toggle a state of the chip select. A number of data strobe signals sent by the memory module in response to the read command are counted. A determination is made whether the memory module is in a pass state or an error state based on a result of the counting.
