Publication number: 20240428850Abstract: A static random access memory (SRAM) has one or more arrays of memory cells, each array of memory cells activated in columns by a wordline. The activated column of memory cells asserts output data onto a plurality of bitlines coupled to output drivers. The SRAM includes a wordline controller generating a variable pulse width wordline which may be reduced sufficient to introduce memory read errors. Each of a high error rate, medium error rate, low error rate, and error-free rate is associated with a pulse width value generated by the wordline controller which is thereby able to associate a wordline pulse width to an associated error rate for performing tasks which are insensitive to a high error rate or a medium error rate, which are specific to certain neural network training and inference using various NN data types.Type: ApplicationFiled: July 15, 2024Publication date: December 26, 2024Applicant: Ceremorphic, Inc.Inventors: Jay A.

Patent number: 11689443Abstract: A node mesh contains an originating node and several node groups, each node group consisting of one or more nodes with interfaces connected to other nodes of the node group. Each node of a node group has an associated route table with an association between an applied DC voltage and an output interface to couple the input signal to. When the originating node outputs a DC voltage accompanied by differential signaling, each node in turn directs the DC voltage and differential signaling to an output interface as directed by the node local route table to a local termination in a node, which may be coupled to a training processor of inference processor for machine learning applications.Type: GrantFiled: May 29, 2021Date of Patent: June 27, 2023Assignee: Ceremorphic, Inc.Inventors: Robert Wiser, Venkat Mattela, Wei Xiong

Publication number: 20220415827Abstract: A plurality of integrated circuits each have a central interconnect region which is enclosed by an inner sealring, optional intermediate sealrings, and an outer sealring. Each sealring has a sealring gap for passage of a signal trace which connects a central interconnect of a first integrated circuit to a central interconnect of a second integrated circuit. In first example of the invention, the signal trace remains on a single layer and routes through sealring layer gaps between the first and second IC. In a second example of the invention, vias are used in gaps between sealrings for the signal trace to change layers such that the sealring gaps are not on the same layer. In a third example of the invention, the vias of the second example are replaced by capacitors with plates in adjacent layers.Type: ApplicationFiled: January 31, 2022Publication date: December 29, 2022Applicant: Ceremorphic, Inc.Inventor: Robert Wiser
