  • Publication number: 20240071553
    Abstract: An example method of performing memory access operations comprises: receiving a request to perform a memory access operation with respect to a set of memory cells connected to a wordline of a memory device; identifying a block family associated with the set of memory cells; determining, for each logical programming level of a plurality of logical programming levels, a corresponding default block family error avoidance (BFEA) threshold voltage offset value associated with the block family; determining a value of a data state metric associated with the set of memory cells; responsive to determining that the value of the data state metric satisfies a threshold criterion, determining, for each logical programming level of a plurality of logical programming levels, a corresponding sub-BFEA threshold voltage offset value; and performing the memory access operation by applying, for each logical programming level of the plurality of logical programming levels, a combination of the default BFEA threshold voltage value

  • Patent number: 8941980
    Abstract: An electronic device assembly includes an electronic device, a rotatable member rotatably attached to the electronic device about a first shaft, and a peripheral device rotatably attached to the rotatable member about a second shaft. The rotatable member and the peripheral device are located on a front side of the electronic device. The peripheral device is rotatable about the second shaft relative to the rotatable member, for allowing the rotatable member and the peripheral device to be located on a same plane. The rotatable member is rotatable about the first shaft relative to the electronic device, for allowing the rotatable member and the peripheral device to be cooperatively attached to a back side of the electronic device.

  • Patent number: 8605429
    Abstract: An all in one computer includes an enclosure and a support module attached to the enclosure. The support module includes a leg stand rotatably attached to a rear panel of the enclosure about an axis perpendicular to the rear panel. The leg stand includes a shorter base and a longer base. An operation opening is defined in the leg stand and located adjacent to the longer base. The leg stand is rotatable between a first position where the longer base faces downward to support the enclosure, and a second position where the longer base faces upwards for facilitating using the operation opening to carry the all in one computer.

  • Patent number: 8553403
    Abstract: An exemplary foldable electronic device includes a processing portion, a keyboard, and a latching member. The processing portion includes a main housing. The keyboard is rotatably connected to the processing portion. The keyboard includes a metal housing. The latching member is arranged in the main housing. The latching member includes a magnet. When the keyboard abuts against the processing portion, the attraction force between the magnet and the metal housing is greater than the force of the gravity acting on the keyboard, the keyboard is attached to the processing portion.
