The voltage level of the common mode is selected to be sufficiently high in order to prevent from punch through while at the same time sufficiently low to maintain the lateral electric field for erase operation to function optimally.

Abstract: An error correction code generator uses an additional static random access memory (SRAM) or a multi-symbol encoder to improve the encoding efficiency.

Hence, the efficiency of the data access of the DRAM is improved and the encoding time of the error correction code generator is reduced.
