  • Patent number: 12156589
    Abstract: A multifunctional table includes a table body, a carrier member, and a holder. The table body includes a board and a support member connected to each other. The board has a table top and a groove. The carrier member is connected to the table body and includes a first slideway. The holder includes a slidable attaching portion and a holding portion connected to each other. The holding portion includes a first holding surface. The first holding surface corresponds to the groove when the slidable attaching portion is slidably attached to the first slideway in a first attached state. A holder includes a slidable attaching portion and a holding portion connected to each other. The holding portion includes a first holding surface and a second holding surface opposite to each other. The first holding surface and the second holding surface are asymmetrical about a central x axis of the holder.

  • Publication number: 20240296877
    Abstract: A memory apparatus and method of operation are provided. The apparatus includes memory cells connected to word lines and disposed in memory holes coupled to bit lines. A control means successively applies each of a series of pulses of a program voltage to selected ones of the word lines while simultaneously applying one of a bit line program voltage and a bit line inhibit voltage to ones of the bit lines coupled to the memory holes containing groups of the memory cells connected to the selected ones of the plurality of word lines to program the groups of the memory cells with data. The control means maintains a voltage applied to ones of the plurality of bit lines as the bit line inhibit voltage in response to the ones of the plurality of bit lines remaining unselected when programming a next one of the groups of the memory cells.

  • Patent number: 12079496
    Abstract: Technology is disclosed herein for managing timing parameters when programming memory cells. Timing parameters used sub-clocks in an MLC program mode may also be used for those same sub-clocks in a first SLC program mode. However, in a second SLC program mode a different set of timing parameters may be used for that set of sub-clocks. Using the same set of timing parameters for the MLC program mode and the first SLC program mode saves storage space. However, the timing parameters for the MLC program mode may be slower than desired for SLC programming. A different set of timing parameters may be used for the second SLC program mode to provide for faster program operation. Moreover, the different set of timing parameters used for the faster SLC program mode do not require storage of a separate set of timing parameters.

  • Publication number: 20240274200
    Abstract: A memory apparatus and method of operation are provided. The apparatus includes memory cells connected to word lines and disposed in strings and configured to retain a threshold voltage corresponding to one of a plurality of data states. A control means is coupled to the word lines and the strings and is configured to successively apply one of a series of pulses of a program voltage to each selected one of the word lines to program the memory cells connected thereto during a program operation. The control means is also configured to utilize a time of a preliminary period of the program operation based on the one of the series of pulses of the program voltage being applied. The preliminary period of the program operation is before the series of pulses of the program voltage are applied to each selected one of the plurality of word lines.

  • Patent number: 12047165
    Abstract: This application relates to a slot negotiation method and a device. The method includes: A transmitter sends a first FlexE overhead frame to a receiver, to request active/standby calendar switching. When the receiver is in a restart state, the receiver does not respond to the received first FlexE overhead frame. In addition, the RX sends a routine update second FlexE overhead frame to the transmitter. Determining that the second FlexE overhead frame is not a response to the first FlexE overhead frame, the transmitter sends a third FlexE overhead frame to request active/standby calendar switching again. According to the method in this application, incorrect calendar switching on the transmitter side caused by a mistaken response of the receiver can be avoided. This reduces the likelihood of a service interruption caused by the existing slot negotiation mechanism.
