Abstract
Memory devices and methods for operating the same are provided. A memory device can include at least one command contact and at least one data contact. The memory device can be configured to detect a condition in which the at least one command contact is connected to a controller and the at least one data contact is disconnected from the controller, and to enter, based at least in part on detecting the condition, a first operating mode with a lower nominal power rating than a second operating mode. Memory modules including one or more such memory devices can be provided, and memory systems including controllers and such memory modules can also be provided.
Claims17
A memory system, comprising:
- a controller;
- and
- at least one memory module coupled to the controller, the at least one memory module including a plurality of memories, each of the plurality of memories including:
- at least one command contact, and
- at least one data contact,
- wherein at least one of the plurality of memories is configured to:
- detect a condition in which the at least one command contact thereof is connected to the controller and the at least one data contact thereof is disconnected from the controller
- enter, based at least in part on detecting the condition, a reduced-power mode.
A memory system, comprising:
- a memory controller;
- and
- at least one memory interface coupled to the memory controller, the memory interface configured to receive a connector of a memory device, the memory interface including:
- a plurality of memory interface data contacts configured to connect to connector data contacts of the connector of the memory device, wherein at least one of the plurality of memory interface data contacts is electrically disconnected from the memory controller and coupled to an electrical ground.
