Patent number: 11978971Abstract: Toolless Compression Attached Memory Module (CAMM) installation systems and methods employ a bolster plate with a generally flat, parallelepiped body portion configured to contact one surface of a CAMM Printed Circuit Board (PCB) and provide compression between the CAMM and a z-axis compression connector. The bolster plate body defines (a) ramped keyhole(s), each ramped keyhole converts lateral displacement of the bolster plate into vertical displacement, providing the compression between the CAMM and the z-axis compression connector, by the ramped keyhole(s) sliding along (a) bottom face(s) of (a) head(s) of (a) fixed standoff(s) extending from an information handling system (IHS) PCB, through the z-axis compression connector and the CAMM PCB. The bolster plate may lock in place, laterally displaced, to maintain the compression between the CAMM and the z-axis compression connector. The bolster plate may also have a flange portion extending generally perpendicular from the body portion.Type: GrantFiled: July 15, 2021Date of Patent: May 7, 2024Assignee: Dell Products, L.P.Inventors: Glenn Chiappe, Jason Scott Morrison

Patent number: 11972803Abstract: A memory device that uses different programming parameters base on the word line(s) to be programmed is described. The programming parameter PROGSRC_PCH provides a pre-charge voltage to physical word lines. In some instances, the PROGSRC_PCH voltage is decoupled, and a new PROGSRC_PCH represents an adjusted (e.g., increased) pre-charge voltage for a certain physical word line or word line zone (i.e., predetermined group of word lines). Using different PROGSRC_PCH voltages can limit or prevent Vt distribution window degradation, particularly for relatively low physical word lines. Additionally, the overall programming time and average current consumed can also be reduced.Type: GrantFiled: January 7, 2022Date of Patent: April 30, 2024Assignee: SanDisk Technologies, LLCInventors: Yu-Chung Lien, Fanqi Wu, Jiahui Yuan
