Abstract: Described systems, apparatuses, and methods relate to volatile memories that are refreshed to maintain data integrity, such as dynamic random-access memory (DRAM) and synchronous DRAM (SDRAM). A memory device includes multiple dies, with each die having a memory array to be refreshed. The multiple dies may be interconnected via at least one inter-die bus of the memory device. A memory controller sends a command to the memory device to enter a self-refresh mode. In response, a die of the multiple dies can enter the self-refresh mode and initiate or otherwise coordinate refresh operations of the other dies. To do so, the die may transmit at least one refresh-related command to at least one other die using the inter-die bus. Multiple different signaling schemes and timing approaches are disclosed. The described inter-die refresh control principles may be implemented in energy-efficient applications, such as in low-power double data rate (LPDDR) SDRAM.

Abstract: Systems, apparatuses, and methods related to a memory device, such as a low-power dynamic random-access memory (DRAM), and an associated host device are described. The memory device includes control circuitry that can determine an operational status of the memory device (e.g., whether the memory device is currently performing a self-refresh operation). The control circuitry can also transmit a signal indicative of the operational status to the host device in response to receiving a command directing the memory device to exit a self-refresh mode. The host device can operate based on the signal. The signal may therefore allow the memory device, the host device, or both to manage operations, including whether to send, receive, or process commands and data read/write requests during times that may be associated with self-refresh operations.
