  • Patent number: 11966631
    Abstract: A method and system for maintaining command queue order are disclosed. According to certain embodiments, commands are read from a host, storing command queue IDs in an array that will keep the queue IDs in order. After having the queue IDs stored in the array, the commands are processed in the data storage device (DSD). After processing, the commands are provided to a completion order adjustment module that will order the commands in queue ID order for sequential commands to be returned to the host. In certain embodiments, for a sequential command, other commands of the same sequence are searched for the array and ordered with the sequential command. If a particular command of the sequence is not found, the completion order adjustment module will wait to transfer the sequence until each command of the sequence is found. For commands not part of a sequence, these commands are transferred to the host.

  • Patent number: 11925026
    Abstract: Disclosed are novel structures and methods for 3D NVM built with vertical transistors above a logic layer. A first embodiment has a conductive film under the transistors and serving as a common node in a memory block. The conductive film may be from a semiconductor layer used to build the transistors. Metal lines are disposed above the transistors for connection through 3D vias to underlying circuitry. Contact plugs may be formed between transistors and metal lines. The conductive film may be coupled to underlying circuitry through contacts on the conductive film or through interconnect vias underneath the film. A second embodiment has conductive lines disposed under the transistors. Either of conductive lines and metal lines may serve as source lines and the other as bit lines for the memory. For low parasitic resistances, the conductive lines may be shorted to bypass metal lines residing in underlying logic layer.

  • Publication number: 20230104818
    Abstract: Disclosed are novel structures and methods for 3D CMOS integrated circuits built with vertical transistors. A gate extension is selectively patterned by first patterning a sacrificial dielectric disposed on a gate material. A 3D CMOS IC comprises vertical transistors of one type constructed in one level and those of an opposite type in another level. The gate of lower-level vertical transistors may be coupled to a top interconnect directly through a 3D gate contact or indirectly through an upper-level via and a lower-level contact. A common-gate coupling may be formed between vertical transistors in different levels through a strapping contact or a gate via. A common-drain coupling may be formed between vertical transistors in different levels by forming upper-level vertical transistor on a piece of conductive film disposed over lower-level vertical transistor with or without an intervening top contact for lower-level vertical transistor.
