  • Patent number: 11921579
    Abstract: A method of operating a memory device is provided. The method includes: receiving a first command from a controller; activating a page of a memory cell array based on the first command; reading data of the activated page; detecting an error from the read data; correcting the detected error to generate error correction data; writing back the error correction data to the activated page in based on the detected error being a single-bit error; and blocking write-back of the error correction data to the activated page based on the detected error being a multi-bit error.

  • Patent number: 8504166
    Abstract: Provided is a deep brain stimulation (DBS) device that wirelessly receives microwaves from a power transmission antenna installed at a hat put on a patient, transforms the microwaves into power, and drives electrodes implanted into a brain of the patient using the power, so as to correct abnormal motor and sensory functions of the patient. The DBS device includes: a hat module configured for placement over a head of the patient to transmit microwaves, and an implantation module configured to be implanted through a skull under a scalp to contact the cerebral nerve of the patient, receive the microwaves from the hat module, transform the microwaves into direct current (DC) power, and stimulate the cerebral nerve using the DC power.

  • Patent number: 8498717
    Abstract: Provided is a neural electronic interface (NEI) device that includes: a deep brain monitoring and stimulation (DBMS) module that wirelessly receives power from a power transmitter at a hat put on a patient, monitors a state of a brain of the patient by collecting various signals of the brain through a probe pin device (PPD), and transmits the collected signals to a communicator of the hat, wherein a remote controller of the hat analyzes the collected signals and controls the DBMS through the controller to stimulate the brain.

  • Patent number: 8412344
    Abstract: Provided is a deep brain stimulation (DBS) device having power wirelessly fed by magnetic induction. A rotating magnetic field is formed using a rotating magnetic field disk installed inside a hat of a patient. The rotating magnetic field generates induced power using an induction coil plate fixed underneath a scalp of the patient to drive electrodes implanted into a brain of the patient so as to correct abnormal motor and sensory functions of the patient using power wirelessly fed from an external device into the electrodes. The DBS device includes: a hat module installed inside a hat of the patient to generate a rotating magnetic field; and an implantation module implanted through a skull under a scalp to contact a nervous system of the patient and combined with the rotating magnetic field of the hat module to stimulate the cerebral nerve using induced power generated by the magnetic induction.
