Publication number: 20230360708Abstract: Memory systems with flexible erase suspend-resume operations are described herein. In one embodiment, a memory device is configured to receive an erase suspend command while a first erase pulse of an erase operation is at a flattop voltage. In response, the memory device suspends the erase operation. The memory device further resumes the erase operation such that a second erase pulse of the erase operation is ramped to the flattop voltage. Absent intervening erase suspend operations, erase operations of the memory device can include a single erase pulse that remains at the flattop voltage for a total duration. A first total duration plus a second total duration the first and second erase pulses, respectively, remain at the flattop voltage remains less than or equal to the total duration the single erase pulse remains at the flattop voltage.Type: ApplicationFiled: May 9, 2022Publication date: November 9, 2023Inventors: Pitamber Shukla, Jiun-Horng Lai, Ching-Huang Lu, Fulvio Rori, Wai Ying Lo, Scott A.

Patent number: 5840146Abstract: The coating of a RF active material on a non-RF active substrate material of typical thickness for packaging purposes, can generate sufficient thermal energy to effect strong bonding of the substrate materials. The RF active material may be-deposited on less than the entire inner surface area of the substrate material, preferably, at or near the portion of the substrate surface which represents the heat seal interface. In this manner of application, additional coating or printing of other substances on the substrate surface can be achieved without hampering the heat sealing process. Flexible medical containers capable of containing a product which is maintained and removed under sterile conditions, can be constructed on commercial production machines from these coated non-RF active substrate materials.Type: GrantFiled: June 6, 1995Date of Patent: November 24, 1998Assignee: Baxter International Inc.Inventors: Lecon Woo, Ying Lo, Michael T.
