    Abstract: A solid-state drive (SSD) may include a volatile buffer such as DRAM, a non-volatile memory (NVM) such as NAND Flash connected to the volatile buffer, and a capacitor connected to both, where the capacitor may have an energy capacity insufficient to supply the buffer and NVM using a normal supply voltage in a normal mode, but sufficient to supply the buffer and NVM using at least one reduced supply voltage in a temporary mode; and a related method may include programming data to the NVM by temporarily reducing the supply voltage to the NVM, and writing data to the NVM using the reduced supply voltage.

    Abstract: A memory controller includes a joint source-channel encoder circuit and a joint source-channel decoder circuit. The joint source-channel encoder circuit source encodes received data independent of whether the received data is compressible data, performs error correction coding on the source encoded data, and stores the source encoded data in a memory device. The joint source-channel decoder circuit performs source decoding of the data read from the memory device between iterations of error correction coding of the read data, and outputs the read data to at least one of a buffer memory and a storage device interface. The joint source-channel decoder circuit performs the source decoding of the read data independent of whether the read data is compressed data.

    Abstract: A memory device includes a memory including memory cells, each of the memory cells being configured to store multiple bits of data. The memory device includes a controller configured to map the levels of the memory cells to bits such that a first half of the levels have a bit with a first binary value in a desired bit position and a second half of the levels have a bit with a second binary value in the desired bit position. The first half of the levels are a first group of consecutive levels, and the second half of the levels are a second group of consecutive levels. The controller is configured to generate a distribution for writing the data to the memory cells based on the mapping, and write the data to the memory cells based on the determined distribution.

    Abstract: A method of operating a memory device is provided. The memory device includes a plurality of multi-level memory cells of which each memory cell includes L levels. Data which is expressed in a binary number is received. A P-length string is generated from the data. The P-length string is converted to a Q-length string. The Q-length string is distributed using I levels by eliminating at least one level from the L levels. P and Q represent binary bit lengths of the P-length string and the Q-length string. Q is greater than P. L represents a maximum number of levels which each multi-level memory cell has. I is smaller than L. The Q-length string is programmed into the plurality of memory cells.
