Abstract: Described apparatuses and methods provide automated error correction with memory refresh. Memory devices can include error correction code (ECC) technology to detect or correct one or more bit-errors in data. Dynamic random-access memory (DRAM), including low-power double data rate (LPPDR) synchronous DRAM (SDRAM), performs refresh operations to maintain data stored in a memory array. A refresh operation can be a self-refresh operation or an auto-refresh operation. Described implementations can combine ECC technology with refresh operations to determine a data error with data that is being refreshed or to correct erroneous data that is being refreshed. In an example, data for a read operation is checked for errors. If an error is detected, a corresponding address can be stored. Responsive to the corresponding address being refreshed, corrected data is stored at the corresponding address in conjunction with the refresh operation. Alternatively, data being refreshed can be checked for an error.

Abstract: Apparatuses and techniques for implementing an asymmetric read-write sequence for interconnected dies are described. The asymmetric read-write sequence refers to an asymmetric die-access sequence for read versus write operations. The “asymmetric” term refers to a difference in an order in which data is written to or read from interface and linked dies of the interconnected die architecture. The orders for the read and write operations can be chosen such that a delay associated with transferring data between the interconnected dies occurs as data passes between the interface die and a memory controller. With asymmetric read-write burst sequences, overall timing of the read and write operations of a memory device may be impacted less, if at all, by a timing delay associated with the interconnected die architecture.

Abstract: Apparatuses, systems, and methods for refresh rate register adjustment based on a targeted refresh queue. A memory includes a temperature sensor which measures a temperature of the memory. The memory also includes a targeted refresh queue which stores identified aggressor addresses. A value of a refresh rate register is set based on both the measured temperature and the number of addresses in the queue. A controller of the memory reads the value of the refresh rate register and provides a refresh signal with timing based on the refresh rate register. In some embodiments, a ratio of targeted and normal refresh operations is adjusted based on how many addresses are in the targeted refresh queue.
