Abstract: Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a battery state associated with the memory system or sub-system may be used as an indicator or basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a battery state or condition satisfies a criterion. Based on determining that the criterion is satisfied the, the garbage collection operation may be postponed until the battery state changes to satisfy a different battery condition.

Abstract: Apparatuses and methods related to memory authentication. Memory devices can be authenticated utilizing authentication codes. An authentication code can be generated based on information stored in a fuse array of the memory device. The authentication code can be stored in the memory device. The stored authentication code can be compared to a captured authentication code based on fuse array information broadcast to memory components of the memory device. The authenticity of the memory device can be determined based on the comparison and can result in placing the memory device in an unlocked state.

Abstract: Semiconductor devices with antennas and electromagnetic interference (EMI) shielding, and associated systems and methods, are described herein. In one embodiment, a semiconductor device includes a semiconductor die coupled to a package substrate. An antenna structure is disposed over and/or adjacent the semiconductor die. An electromagnetic interference (EMI) shield is disposed between the semiconductor die and the antenna structure to shield at least the semiconductor die from electromagnetic radiation generated by the antenna structure and/or to shield the antenna structure from interference generated by the semiconductor die. A first dielectric material and/or a thermal interface material can be positioned between the semiconductor die and the EMI shield, and a second dielectric material can be positioned between the EMI shield and the antenna structure. In some embodiments, the semiconductor device includes a package molding over at least a portion of the antenna, the EMI shield, and/or the second dielectric material.

Abstract: Apparatuses and methods related to detecting synchronization between multiple devices. The security of a device may be compromised if the device receives commands from unauthorized sources. A state of a device can be affected by the commands the device receives. A different device can determine whether there is synchronicity between device and the different device to determine whether the security of the device may have been compromised.

Abstract: Methods of operating a memory having a first pool of memory cells having a first storage density and a second pool of memory cells having a second storage density greater than the first storage density, as well as apparatus configured to perform similar methods, might include determining whether a value of an indication of available power is less than a threshold, and, in response to determining that the value of the indication of available power is less than the threshold, increasing a size of the first pool of memory cells, limiting write operations of the memory to the first pool of memory cells, and postponing movement of data from the first pool of memory cells to the second pool of memory cells.

Abstract: Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a criticality value can be determined and used as a basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a criticality value associated with performing a garbage collection operation satisfies a condition. Based on determining that the condition is satisfied, a parameter associated with performing the garbage collection operation can be adjusted. The garbage collection operation is performed on the data block stored on the memory component using the adjusted parameter.
