Abstract: A computing device for verifying data integrity is provided, comprising a memory controller configured to receive a plurality of original data blocks. Each original data block has an associated initial CRC value. The memory controller then segments and recombines the received data blocks into logic blocks, and calculates a new logic block CRC value for each logic block. The logic blocks are transmitted with their respective new logic block CRC values to a storage device, and the logic blocks are written to non-volatile memory of the storage device in a write operation. After the write operation, a combined CRC value is calculated for the logic blocks and a combined CRC value for the original data blocks, and compare the combined CRC values. The memory controller determines whether the combined CRC values match. When they match, the memory controller generates a verification response verifying the integrity of the write operation.

Abstract: Disclosed are a solid state drive and a write operation method. The solid state drive comprises: a controller, receiving write data from outside and comprising a first cache unit for storing the write data; a Flash memory, receiving the write data sent by the first cache unit according to a first instruction of the controller; a second cache unit, storing the write data from the first cache unit as backup data, and sending the backup data to the Flash memory according to a second instruction of the controller.

By combining advantages of the first and second cache units, efficiency and quality of write operations are improved and bandwidth requirements are lowered.

Abstract: In a probabilistic amplitude shaping (PAS) system, a distribution matching (DM) component may receive a uniform bit sequence with equal probabilities, which may be converted into symbols with a desired probability distribution (e.g., Gaussian). For example, the probability distribution may use inner constellation points associated with a lower energy and/or power more frequently and outer constellation points associated with a higher energy and/or power less frequently. In general, the DM component may map binary bits to positive amplitudes with a non-uniform distribution according to a DM rate that is based at least in part on a signal-to-noise ratio (SNR), which may vary significantly in a spatial and frequency selective wireless channel. Accordingly, some aspects described herein relate to configuring DM parameters and codeword and resource mappings in a spatial and frequency selective wireless channel.
