Abstract: Power management circuitry in the solid state drive monitors activity on the plurality of media channels to coordinate an active period and an idle period using credits to manage a power budget for the solid state drive. The power management circuitry to coordinate active and idle periods across components in a workload pipeline in the solid state drive for a given performance target to obtain an optimal power and thermal profile.

Abstract: Dirty Logical-to-Physical (L2P) entries in an L2P indirection table stored in a host volatile memory buffer are flushed to non-volatile memory in the solid state drive through the use of a write-back mode based on flush checkpoints. The use of write-back mode to flush dirty entries in the L2P indirection table to non-volatile memory in the solid state drive based on flush checkpoints results in an increase in the write bandwidth of the solid state drive.

Abstract: A solid state drive with a Logical To Physical (L2P) indirection table stored in a persistent memory is provided. The L2P indirection table has a plurality of entries, each entry to store a physical block address in the block addressable memory assigned to a logical block address. The solid state drive including solid state drive controller circuitry communicatively coupled to the persistent memory and the block addressable memory. The solid state drive controller circuitry including a volatile memory to store a logical to physical address indirection table cache and circuitry to monitor the logical to physical address indirection table cache and to write dirty logical to physical entries in the logical to physical address indirection table cache to the logical to physical address indirection table in the persistent memory.

Abstract: A solid state drive (SSD) includes different segments of nonvolatile (NV) storage media with different access times. The NV media segment with faster access time operates as a cache for the segment with the slower access time. The SSD implements idle eviction from the cache segment to the other segment based on an idle condition of the SSD. The SSD can dynamically change application of the idle eviction based on a power management state indicated for the hardware platform. Thus, a change in power management state of the hardware platform associated with the SSD can cause the SSD to implement idle eviction differently.

Abstract: An apparatus is described that includes a solid state drive having non volatile buffer memory and non volatile primary storage memory. The non volatile buffer memory is to store less bits per cell than the non volatile primary storage memory. The solid state drive includes a controller to flush the buffer in response to a buffer flush command received from a host. The controller is to cause the solid state drive to service read/write requests that are newly received from the host in between flushes of smaller portions of the buffer's content that are performed to service the buffer flush command.

Abstract: A method and circuit for programming an output buffer having a first output driver for producing a first signaling level with a first programmable strength and a second output driver for producing a second signaling level with a second programmable strength. The method includes coupling a test resistor between a source of the second signaling level and a mode terminal, sensing a first level at the mode terminal, and uncoupling the test resistor from the mode terminal. If the first level is between the second signaling level and a reference level, then programming the output buffer with reference to an unterminated transmission line coupled to the mode terminal. Otherwise, programming the output buffer with reference to an external resistor coupled between a source of the first signaling level and the mode terminal. The circuit includes a first counter coupled to the first comparator to produce a first value responsive to the mode flag, the mode terminal, and the reference level.
