Abstract
A memory system is provided. The memory system includes a memory controller and a data bus electrically coupled to the memory controller. The memory system further includes one or more memory devices communicatively coupled to the memory controller via the data bus, wherein the memory controller is configured to derive a read profile for each of the one or more memory devices to account for a time propagation delay of data being sent via the data bus during read operations of the one or more memory devices.
Claims20
A memory system, comprising:
- a memory controller,
- a data bus electrically coupled to the memory controller;
- and
- one or more memory devices communicatively coupled to the memory controller via the data bus, wherein the memory controller is configured to derive a read profile for each of the one or more memory devices to account for a time propagation delay of data being sent via the data bus during read operations of the one or more memory devices.
A method for adjusting a read output timing in a memory system, comprising:
- deriving a read profile by observing a timing delay of data being sent from a memory device included in the memory system to a memory controller included in the memory system;
- storing the read profile in the memory device;
- and
- applying the read profile to adjust the read output timing of the data during operations of the memory system.
A memory device, comprising:
- a memory array having at least one memory cell;
- and
- a read output timing adjustment circuit configured to derive a read profile to adjust a read output timing of data being read from the memory device by a memory controller during read operations of the memory array, wherein the memory device is communicatively coupled to the memory controller via a data bus shared with a plurality of memory devices.
