Abstract: Embodiments of the present disclosure disclose a memory system and operation method thereof, a memory controller and a memory. The memory system includes a memory. The memory includes a memory cell array and a peripheral circuit coupled to the memory cell array. The memory cell array includes memory cells capable of storing m bits of information, and m is a positive integer greater than 1. The operation method includes: determining, by the peripheral circuit, (n+1)th group of page data according to a received prefix command and received n groups of page data, wherein n is a positive integer, and n+1 is a positive integer less than or equal to m; and writing the n groups of page data and the (n+1)th group of page data into the memory cell array to generate 2n different data states in the memory cell array.

Abstract: A method for verifying a low-density parity-check (LDPC) unit capable of being applied in a memory system can include receiving original data corresponding to a memory device, encoding the original data by the LDPC unit to be verified, injecting errors into the encoded original data by a data pattern for generating verifying data, and verifying a soft decode capability of the LDPC unit by utilizing the verifying data. The data pattern can include the errors generated by threshold voltage (Vth) distributions interlaced between two neighboring logic states of 2n logic states of the memory device. The method and system can provide an error injection to accurately and efficiently verify a LDPC soft decode capability of the LDPC unit, decrease errors, increase error correction accuracy and efficiency, more accurately model actual threshold voltage (Vth) distributions, increase flexibility, increase speed, increase performance, and reduce firmware overhead.

Abstract: An elastic object rendering method and apparatus, a device, and a storage medium are provided. The method comprises: constructing a grid model of an elastic object in response to a deformation trigger operation for the elastic object, first determining the deformation position and speed of an acted point in the grid model of the elastic object under the deformation trigger operation; determining the motion trajectory of each grid point in the grid model of the elastic object according to the deformation position and speed of the acted point, and the elastic constraint of each grid point in the grid model of the elastic object; and finally, according to the motion trajectory of each grid point in the grid model of the elastic object, invoking the grid model of the elastic object to perform elastic motion.

Abstract: A scene controlling method, a device and electronic equipment are provided, which relate to the field of scene controlling. The scene controlling method includes displaying a scene in a first modality, recognizing a trigger object, determining a motion of the trigger object, and switching the scene from the first modality to a second modality based on the motion. The first modality of the scene is associated with the second modality of the scene. Predetermined scene information is retrieved based on the motion of the trigger object so as to switch between scenes or control an element in the scene. By associating the motions of the trigger object with the scenes, the scene displayed on the electronic equipment can be controlled without any hardware upgrade of the conventional electronic equipment, thereby reducing the cost.
