Patent number: 11593306Abstract: The subject technology selects a most recently created file from a set of files stored in a source table. The subject technology iterates, in the source table, starting from the most recently created file up to an age threshold to select a first set of files for performing a first defragmentation process. The subject technology sets an indication corresponding to a particular file that is a last file, from the first set of files, that meets the age threshold. The subject technology performs the first defragmentation process on the selected first set of files. The subject technology determines that the first defragmentation process was successful.Type: GrantFiled: January 28, 2022Date of Patent: February 28, 2023Assignee: Snowflake Inc.Inventors: Harry Liu, Ryan Michael Thomas Shelly, Jiaqi Yan

Publication number: 20080106955Abstract: A Static Random Access Memory (SRAM) having a split write control is described. The SRAM includes bit, write, and write-word lines. Each memory cell within the SRAM includes a delay which is coupled to a dedicated write-word line. When a cell is not being written, its delay receives a delay signal on its associated write-word line, which increases the response time of the cell. When a cell is to be written, however, its delay receives a bypass signal on its associated write-word line, which decreases the response time of the SRAM cell.Type: ApplicationFiled: January 14, 2008Publication date: May 8, 2008Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Keith Golke, Harry Liu, David Nelson

Publication number: 20070242537Abstract: A radiation hardened memory element includes at least two delay elements for maintaining radiation hardness. In an example, the memory element is an SRAM cell. Both delays are coupled together in series so that if either one of the delays fails, a delay will still be maintained within the SRAM cell. The critical areas of the delays may be positioned so that a common line of sight cannot be made between each delay and a circuit node.Type: ApplicationFiled: March 27, 2006Publication date: October 18, 2007Applicant: Honeywell International Inc.Inventors: Keith Golke, Harry Liu, Michael Liu, David Nelson

Patent number: 7233518Abstract: A method and system is disclosed for preventing write errors in a Single Event Upset (SEU) hardened static random access memory (SRAM) cell. A compensating element has been connected to a feedback path of the SRAM cell. The compensating element operates to cancel out capacitive coupling generated in an active delay element of the SRAM cell. If the compensating element sufficiently cancels the effects of the capacitive coupling, a write error will not occur in the SRAM cell. The compensating element also occupies a smaller silicon area than other proposed solutions.Type: GrantFiled: February 4, 2005Date of Patent: June 19, 2007Assignee: Honeywell International Inc.Inventor: Harry Liu

Patent number: 7200031Abstract: A method and system is disclosed for reducing proton and heavy ion SEU sensitivity of a static random access memory (SRAM) cell. A first passive delay element has been inserted in series with an active delay element in a first feedback path of the SRAM cell, and a second passive delay element has been inserted in a second feedback path of the SRAM cell. The passive delay elements reduce the proton SEU sensitivity of the SRAM cell, and the active delay element reduces the heavy ion sensitivity of the SRAM cell. The passive delay elements also protect the SRAM cell against SEUs that may occur when the SRAM cell is in dynamic mode.Type: GrantFiled: March 16, 2005Date of Patent: April 3, 2007Assignee: Honeywell International, Inc.Inventors: Michael Liu, Harry Liu
