摘要： Power saving techniques for memory systems are disclosed. In particular, exemplary aspects of the present disclosure contemplate taking advantage of patterns that may exist within memory elements and eliminating duplicative data transfers. Specifically, if data is repetitive, instead of sending the same data repeatedly, the data may be sent only a single time with instructions that cause the data to be replicated at a receiving end to restore the data to its original repeated state. By reducing the amount of data that is transferred between a host and a memory element, power consumption is reduced.

摘要： In one aspect, a method includes splitting empty RAID stripes into sub-stripes and storing pages into the sub-stripes based on a compressibility score. In another aspect, a method includes reading pages from 1-stripes, storing compressed data in a temporary location, reading multiple stripes, determining compressibility score for each stripe and filling stripes based on the compressibility score. In a further aspect, a method includes scanning a dirty queue in a system cache, compressing pages ready for destaging, combining compressed pages in to one aggregated page, writing one aggregated page to one stripe and storing pages with same compressibility score in a stripe.

摘要： A data storage device can have at least a buffer memory, a selection module, and a non-volatile memory. The buffer memory and non-volatile memory may consist of different types of memory while the non-volatile memory has one or more rewritable in-place memory cells. The buffer memory and non-volatile memory may each store data associated with a pending data request as directed by the selection module until a settle time of the rewritable in-place memory cell has expired.

摘要： A method of operating a memory device is provided. The memory device includes a plurality of multi-level memory cells of which each memory cell includes L levels. Data which is expressed in a binary number is received. A P-length string is generated from the data. The P-length string is converted to a Q-length string. The Q-length string is distributed using I levels by eliminating at least one level from the L levels. P and Q represent binary bit lengths of the P-length string and the Q-length string. Q is greater than P. L represents a maximum number of levels which each multi-level memory cell has. I is smaller than L. The Q-length string is programmed into the plurality of memory cells.

摘要： Systems and methods are disclosed for identifying and compressing rarely used data. A storage module may include a memory and a storage controller in operative communication with the memory. The storage controller is configured to identify an access of data stored at a first portion of the memory; determine, based on a first value of the access counter associated with the identified access and a second value of the access counter, that an age of the data stored at the first portion of the memory exceeds a threshold; identify data stored at a second portion of the memory that is associated with a third value of the access counter, where the third value of the access counter is within a range of the first value of the access counter; and compress together at least the data stored at the first and second portions of the memory.
