Abstract: A bonded assembly includes a memory die bonded to a support die. The memory die contains at least one three-dimensional array of memory elements, memory-die dielectric material layers, and memory-die bonding pads. The support die contains at least one peripheral circuitry including complementary metal-oxide-semiconductor (CMOS) devices and configured to generate control signals for, and receive sense signals from, the at least one three-dimensional array of memory elements and a functional module and configured to provide a functionality that is independent of operation of the at least one three-dimensional array of memory elements. The functional module may include an error correction code (ECC) module, a memory module configured to interface with an external processor module located outside of the memory die, a microprocessor unit module, a wireless communication module, and/or a system level controller module.

Abstract: In an illustrative example, a method includes receiving data that includes a set of data symbols. The method further includes generating a set of parity symbols based on the set of data symbols using an erasure correcting code. The set of parity symbols includes at least a first parity symbol that is generated based on a first proper subset of the set of data symbols. The first parity symbol enables recovery of a data symbol of the first proper subset independently of a second proper subset of the set of data symbols.

Abstract: A method of scheduling memory operations to be performed by non-volatile memory devices in a storage system includes identifying a plurality of memory operations to be performed by a plurality of non-volatile memory devices in the storage system. The number of memory operations in the plurality of memory operations is no greater than the number of non-volatile memory devices in the plurality of non-volatile memory devices; each memory operation is to be performed by a distinct non-volatile memory device; and the memory operations include host writes, garbage collection writes, and garbage collection reads. The method also includes, for each non-volatile memory device, assigning preference values to each of the memory operations. The method further includes assigning each memory operation to a distinct non-volatile memory device, using the preference values assigned to each of the memory operations for each non-volatile memory device.
