    摘要: A packaged memory device can include a primary memory die coupled to a shared intra-package communication bus and coupled to an external host device using a host interface bus, and the host interface bus can include a host clock channel. The memory device can include multiple secondary dies coupled to the intra-package communication bus, and each of the secondary dies can be configured to receive the same messages from the primary memory die using the intra-package communication bus. The primary memory die can send a first message to, or receive a first message from, a particular one of the secondary dies using the intra-package communication bus, and the first message can include a first chip identification field that exclusively indicates the particular one of the secondary dies.

    摘要: Methods, systems, and devices for managing memory based on access duration are described. A memory device may include a first set of memory cells resilient against access durations of a first duration and a second set of memory cells resilient against access durations of a shorter duration. A command for accessing the memory device may be received. The command may be associated with an access duration. Whether to access, as part of executing the command, the first set of memory cells or the second set of memory cells may be determined based on the access duration. The first set of memory cells may be accessed, as part of executing the command, based on the access duration being greater than a threshold duration. Or the second set of memory cells may be accessed based on the access duration being less than or equal to the threshold duration.
