Abstract: Methods, systems, and devices for cache management in a memory subsystem are described. An interface controller may include a first buffer and a second buffer. The interface controller may use the first and second buffers to facilitate operating a volatile memory as a cache for a non-volatile memory. During an access operation, the interface controller may use the buffer to transfer data between the volatile memory, non-volatile memory, and another device. In response to the access operation, the interface controller may use the second buffer to transfer second data from the volatile memory to the non-volatile memory.

Abstract: Methods, systems, and devices for compressed logical-to-physical mapping for a memory bypass for error detection and correction are described. A memory device may include error detection and correction circuitry for detecting and correcting errors in data that is read from a memory array of the memory device. To reduce read latencies, the memory device may include bypass circuitry that enables it to transmit the data to the host device before or during error detection. If the memory device determines that the data is erroneous, the memory device may transmit an alert to the host device concurrently with or after transmitting the data. The memory device may perform error correction on the data and store corrected data in a register. Based on receiving an alert, the host device may issue one or more additional read commands to re-read the data from the memory bank or read the corrected data from the register.

Abstract: Methods, systems, and devices for cache metadata management in a memory subsystem are described. The memory subsystem may include an interface controller coupled with a non-volatile memory and a volatile memory. The interface controller may use metadata, such as validity information and dirty information, to operate the volatile memory as cache. The interface controller may store the dirty information in the volatile memory and may store the validity information in an array in the interface controller.

Abstract: Methods, systems, and devices for die voltage regulation are described. A device may include a first die and second die. A component that generates voltage on the first die may be connected to a capacitor on the second die through a conductive line. The conductive line may allow the capacitor on the second die to regulate voltage generated by the component on the first die.

Abstract: Methods, systems, and devices for dynamic page activation are described. In some examples, one or more components of a memory device (e.g., an interface controller of a memory device) may receive a first read command for a first page of data stored at a memory array. The memory device may determine, based on one or more prior access operations, that a second read command for a second page of data may be received. The memory device may prefetch (e.g., read) the second page of data such that when the second read command is received, the data may have already been read and may be communicated (e.g., to a host device) in response to the second read command.
