Publication number: 20240020013Abstract: A method performed by a solid state drive is described. The method includes, on a channel that internally couples a controller of the solid state drive to a storage device of the solid state drive, sending write data for a program operation to be performed by one of the storage device's logical units in separate chunks over the channel. The method also includes inserting higher priority traffic items of other logical units of the storage device in between the separate chunks.Type: ApplicationFiled: September 27, 2023Publication date: January 18, 2024Inventors: David J.

Patent number: 10956081Abstract: A data structure is maintained for performing a program operation that is allowed to be suspended to perform reads in a NAND device, where the data structure indicates a plurality of tiers, where each tier of the plurality of tiers has a number of allowed suspends of the program operation while executing in the tier, and where a sum of the number of allowed suspends for all tiers of the plurality of tiers equals a maximum allowed number of suspends of the program operation. In response to performing a resume of the program operation, after performing a read following a suspend of the program operation, a determination is made of a tier of the plurality of tiers for the program operation and a subsequent suspend of the program operation is performed only after a measure of progress of the program operation has been exceeded in the determined tier.Type: GrantFiled: April 18, 2019Date of Patent: March 23, 2021Assignee: INTEL CORPORATIONInventors: David J.

Patent number: 10521121Abstract: Provided are an apparatus, system and method for apparatus, system and method for throttling an acceptance rate for adding host Input/Output (I/O) commands to a buffer in a non-volatile memory storage device. Information is maintained on an input rate at which I/O commands are being added to the buffer and information is maintained on an output rate at which I/O commands are processed from the buffer to apply to execute against the non-volatile memory. A determination is made of a current level of available space in the buffer and an acceptance rate at which I/O commands are added to the buffer from the host system to process based on the input rate, the output rate, the current level of available space, and an available space threshold for the buffer to maintain the buffer at the available space threshold. I/O commands are added to the buffer to process based on the acceptance rate. The I/O commands are accessed from the buffer to process to execute against the non-volatile memory.Type: GrantFiled: December 29, 2016Date of Patent: December 31, 2019Assignee: INTEL CORPORATIONInventors: David B. Carlton, Xin Guo, Yu Du

Patent number: 10446238Abstract: Embodiments include apparatuses, methods, and computer devices including a multi-level NAND memory array and a memory controller coupled to the multi-level NAND memory array. The multi-level NAND memory array may include a first word line and a second word line. The memory controller may receive a first page of data and a second page of data together with a program command to program the first page of data and the second page of data into the multi-level NAND memory array. The memory controller may program the first page of data into a page of the first word line via a first pass, and further program the second page of data into a page of the second word line via a second pass, subsequent to the first pass. Other embodiments may also be described and claimed.Type: GrantFiled: September 27, 2017Date of Patent: October 15, 2019Assignee: Intel CorporationInventors: Aliasgar S. Madraswala, Xin Guo, David B.
