Title: Dennis S. Ea: Innovator in Nonvolatile Memory Technology
Introduction
Dennis S. Ea is a prominent inventor based in Hayward, CA (US), known for his significant contributions to the field of nonvolatile memory technology. With a total of 6 patents to his name, he has made remarkable advancements that enhance data storage efficiency and reliability.
Latest Patents
One of his latest patents is titled "Data folding in 3D nonvolatile memory." This innovation involves a process where data initially stored in Single Level Cell (SLC) blocks is copied to a Multi Level Cell (MLC) block. The data is stored in MLC format, with the copying occurring in a minimum unit of a fold-set. The MLC block includes multiple separately-selectable sets of NAND strings, allowing data from an individual fold-set to be copied exclusively to two or more word lines of a selected set of NAND strings.
Another notable patent is "Partially-bad block operation in 3-D nonvolatile memory." This invention identifies partially-bad blocks in a 3-D block-erasable nonvolatile memory. Each partially-bad block contains one or more inoperable separately-selectable sets of NAND strings alongside operable sets. The operable sets within multiple partially-bad blocks are identified and mapped to create virtual blocks, which are assigned virtual block addresses for efficient access.
