摘要： In general, this disclosure relates to garbage collection in a storage device. Aspects of this disclosure describe techniques to identify one or more candidate memory storage blocks that should be recycled during garbage collection. The one or more candidate memory storage blocks may be identified based at least on monitored soft metrics of the candidate memory storage blocks. During garbage collection, the identified one or more candidate memory storage blocks may be recycled to free up storage space.

摘要： In general, this disclosure relates to storage of logical blocks in a storage device. Aspects of this disclosure describe techniques to monitor the frequency of access of one or more logical blocks referenced by one or more logical block addresses. Based on the frequency of access, in non-limiting aspects of this disclosure, a controller may select one or more physical blocks of a common memory storage block. The storage device may store the logical blocks in the selected physical blocks.

摘要： An actuator control system for a two-stage actuator system of a disc drive has a first, or primary, stage actuator consisting of a voice coil motor that positions the head relative to a disc and a microactuator that alters the actuator system without operation of the voice coil motor. A control loop includes a controller responsive to seek commands to operate the voice coil motor, thereby moving the head relative to the disc. An active damping circuit is coupled to the head to operate the microactuator to damp resonance modes of the actuator system.

摘要： Method and apparatus for enhancing reliability and integrity of data stored in a non-volatile memory, such as in a solid-state drive (SSD) having an array of flash memory cells. In accordance with various embodiments, a controller is adapted to harden data stored in a first location of said memory in relation to a detected loss of retention characteristics of the first location. In some embodiments, the data are hardened by storing redundancy information associated with said data in a second location of said memory. The redundancy information can be a redundant set of the data or higher level error correct codes (ECC). The hardened data can be recovered to the host during a read operation by accessing the data stored in both the first and second locations.

摘要： The read channel of a solid state non-volatile memory may be configured to compensate for shifts in the threshold voltages of memory cells of the memory. A log of write time information and write temperature information from one or more write operations is stored in a data unit header. The read channel configuration, which may include reference voltages used for the read operation, is determined using the write time information and the write temperature information. Memory cells of the data unit are read using the configured read channel. A historical profile spanning multiple write operations may also be developed and used to configure the read channel.
