Patent number: 11790873Abstract: An electronic display may include a pixel circuit. The pixel circuit may include memory storage to store data values representative of image data to be depicted via the pixel circuit. The memory storage may also include memory components for storing bits of the data value. The pixel circuit may also include a light-emitting device for emitting light based at least in part on the data value and a controller. The controller may receive the data value and store the bits based on a mapping between the bits and the memory components. The mapping may be determined based on routing one or more of the bits associated with one or more defective memory components of the memory components to one or more other memory components of the memory components. The controller may also drive the light-emitting device to emit light based on the bits stored in accordance with the mapping.Type: GrantFiled: August 12, 2022Date of Patent: October 17, 2023Assignee: Apple Inc.Inventors: Stanley Bo-Ting Wang, Derek Keith Shaeffer, Ivan Knez, Jose Antonio Dominguez-Caballero, Tien-Chien Kuo

Patent number: 11675534Abstract: A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to receive a command, such as from a host device, to write data to the memory device, perform toggle mode (TM) encoding on the data, and send the TM encoded data to the memory device. The memory device is configured to receive the TM encoded data, decode the TM encoded data, and write the decoded data to a location within the memory device. The memory device is further configured to receive a read command to read data from a location within the memory device, read the data, TM encode the data, and send the TM encoded data to the controller. The controller is configured to receive and decode the TM encoded data, and send the decoded data to a host device.Type: GrantFiled: October 20, 2022Date of Patent: June 13, 2023Assignee: Western Digital Technologies, Inc.Inventors: Julian Vlaiko, Idan Alrod, Tien-Chien Kuo, Nimrod Hermesh, Eran Sharon

Patent number: 11650756Abstract: A storage apparatus includes non-volatile memory cells formed on a memory die, each memory cell configured to hold bits of data, and a control circuit formed on the memory die. The control circuit is configured to calculate parity data for data to be stored in the memory cells and program the memory cells to first distributions. The control circuit is also configured to read the memory cells in the first distributions, recover the data from results of reading the memory cells in the first distributions combined with the parity data, and further program the memory cells from the first distributions to second distributions to store the data. In some cases, the recovered data may have a high bit error rate. To handle higher bit error rates, the use of soft bit data is incorporated into an encoded foggy-fine scheme.Type: GrantFiled: February 9, 2021Date of Patent: May 16, 2023Assignee: Western Digital Technologies, Inc.Inventors: Idan Alrod, Alexander Bazarsky, Tien-Chien Kuo, Eran Sharon, Jack Frayer, Sergey Anatolievich Gorobets
