Abstract: A method for managing a memory system may include monitoring one or more accesses of a page of memory, determining, based on the monitoring, an access pattern of the page of memory, and selecting, based on the access pattern, a coherency bias for the page of memory. The monitoring may include maintaining an indication of the one or more accesses. The determining may include comparing the indication to a threshold. Maintaining the indication may include changing the indication in a first manner based on an access of the page of memory by a first apparatus. Maintaining the indication may include changing the indication in a second manner based on an access of the page of memory by a second apparatus. The first manner may counteract the second manner.

Abstract: A method for managing a memory system may include monitoring a page of a first memory of a first type, determine a usage of the page based on the monitoring, and migrating the page to a second memory of a second type based on the usage of the page. Monitoring the page may include monitoring a mapping of the page. Monitoring the mapping of the page may include monitoring a mapping of the page from a logical address to a physical address. Determining the usage of the page may include determining an update frequency of the page. Determining the usage of the page may include comparing the update frequency of the page to a threshold. Migrating the page may include sending an interrupt to a device driver. Migrating the page may include setting a write protection status for the page.

Abstract: Inventive aspects include a polar code encoding system, which includes a partitioning unit to receive and partition input data into partitioned input data units. Encoders encode the partitioned input data units, and generate encoded partitioned input data units. Multiplier units perform matrix multiplication on the partitioned input data units and generator matrices, and generate matrix products. Adder units perform matrix addition on the encoded partitioned input data units and the matrix products. A combining unit combines outputs of the encoders into a target code word X. The target code word X may be a length-N code word X, where N=N1+N2+ . . . +Nm, where each of N1, N2, through Nm are a power of two (2).

Abstract: According to one general aspect, an apparatus may include a regeneration-code-aware (RCA) storage device configured to calculate at least one type of data regeneration code for data error correction. The RCA storage device may include a memory configured to store data in chunks which, in turn, comprise data blocks. The RCA storage device may include a processor configured to compute, when requested by an external host device, a data regeneration code based upon a selected number of data blocks. The RCA storage device may include an external interface configured to transmit the data regeneration code to the external host device.
