Patent number: 11971832Abstract: A method can include: receiving a plurality of consecutive commands on a unidirectional command-address (CA) bus input of a discrete nonvolatile memory (NVM) device, the commands being synchronous with a timing clock; for each received command, determining if the command is an express read (NVR) command, if a command is determined to be an NVR command, determining if a next consecutive command is an NVR command, wherein consecutive NVR commands form an NVR command sequence; in response to the no more than the NVR command sequence, accessing read data stored in NVM cells of the NVM device; and driving the read data on parallel data input/outputs (I/Os) of the NVM device in a burst of data values, the data values of the burst being output in synchronism with rising and falling edges of the timing clock; wherein the CA bus input includes a plurality of parallel CA signal inputs. Related memory devices and systems are also disclosed.Type: GrantFiled: December 17, 2020Date of Patent: April 30, 2024Assignee: INFINEON TECHNOLOGIES LLCInventors: Clifford Zitlaw, Stephan Rosner, Hans Van Antwerpen, Morgan Andrew Whately

Patent number: 11934245Abstract: A method is disclosed to estimate energy consumed by a component in a microcontroller during operation including identifying “event” activities, where the energy consumed by the component may be determined by the number of events executed by the component, and “duration” activities, where the energy consumed may be determined by the duration of time required to execute of the activity, and determining the energy consumed by the component based on the number of events/duration of time and an energy coefficient which corresponds to the amount of energy consumed by the component to execute the activity, under given operating conditions. In an embodiment, data transfers at a bus interface may represent event activities. Apparatus to estimate the energy consumed is disclosed including bus monitors to receive signals representing data transfers at a bus interface and provide signals indicating the number of data transfers executed.Type: GrantFiled: May 11, 2021Date of Patent: March 19, 2024Assignee: Cypress Semiconductor CorporationInventors: Christian Wiencke, Hans Van Antwerpen, Stephan Rosner, Roland Richter, Jean-Paul Vanitegem, Jan-Willem Van de Waerdt

Publication number: 20240039732Abstract: A signature graph method is proposed to authenticate shared high-entropy data using a graph that can be easily identified by human eyes (or by computer image recognition algorithms). An example method for authenticating a shared data element comprises receiving a data element to be shared; transforming the data element to be shared into signature graph data, using at least one collision-resistant one-way mapping function; and rendering a human-perceptible representation of the signature graph data, such as an audible and/or visual representation, for perception by a human user. In some embodiments, transforming the data element comprises applying a cryptographic hash function to the data element, to obtain a first hash output, and applying a cryptographic hash function to the first hash output, to obtain the signature graph data.Type: ApplicationFiled: August 1, 2022Publication date: February 1, 2024Applicant: Cypress Semiconductor CorporationInventors: Hui LUO, Hans VAN ANTWERPEN

Patent number: 11586896Abstract: In-memory computing architectures and methods of performing multiply-and-accumulate operations are provided. The method includes sequentially shifting bits of first input bytes into each row in an array of memory cells arranged in rows and columns. Each memory cell is activated based on the bit to produce a bit-line current from each activated memory cell in a column on a shared bit-line proportional to a product of the bit and a weight stored therein. Charges produced by a sum of the bit-line currents in a column are accumulated in first charge-storage banks coupled to a shared bit-line in each of the columns. Concurrently, charges from second input bytes accumulated in second charge-storage banks previously coupled to the columns are sequentially converted into output bytes. The charge-storage banks are exchanged after the first input bytes have been accumulated and the charges from the second input bytes converted. The method then repeats.Type: GrantFiled: June 22, 2020Date of Patent: February 21, 2023Assignee: INFINEON TECHNOLOGIES LLCInventors: Ramesh Chettuvetty, Vijay Raghavan, Hans Van Antwerpen
