The present disclosure relates to a novel tetrahydropyridine derivative compound, a stereoisomer thereof, or a pharmaceutically acceptable salt thereof, methods for preparing the compounds, methods for inhibiting UDP-3-O&#x2014;(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase (LpxC), methods for treating Gram-negative bacterial infections, the use of the compounds for the preparation of therapeutic medicaments for treating Gram-negative bacterial infections, and pharmaceutical compositions for prevention or treatment of Gram-negative bacterial infections, which contain the compounds. The compounds represented by formula I, stereoisomers thereof or pharmaceutically acceptable salts thereof according to the present disclosure can exhibit excellent effects on the treatment bacterial infections.

Tetrahydropyridine derivatives and their use as antibacterial agents

A non-volatile memory may include a plurality of map blocks for storing a plurality of map units, the map units representing mapping information between physical addresses and logical addresses. A storage device may include such a non-volatile memory. A method of mapping such a non-volatile memory may include writing historical information regarding locations of valid map units among the map units included in map blocks previously allocated among the map blocks when a new map block among the map blocks is allocated, the valid map units representing valid mapping information, and constructing a map table including all of the valid mapping information based on the historical information and a result of searching a map block recently allocated among the map blocks.

Storage device and method of mapping a nonvolatile memory based on a map history

A method of writing partial page data in a non-volatile memory device includes, reading data from a second block when the size of a last page of data to be written in a page of a first block is smaller than a size of the page of the first block, wherein a size of the read data is given by the size of the page of the first block minus the size of the last page of data; storing together data of the last page and the data read from the second block in a buffer; and writing the data stored in the buffer in the first block.

Methods of writing partial page data in a non-volatile memory device

An apparatus, memory device controller and method of controlling a memory device are provided. The example apparatus may include a bad block bitmap referencing unit configured to obtain bad block information from a bad block bitmap based on a given memory address, the given memory address being one of a logical memory address and a physical memory address corresponding to the logical memory address, the bad block information indicating whether a given memory block corresponding to the given memory address is a bad block and a memory mapping unit configured to obtain the physical memory address corresponding to the logical memory address, and configured to obtain a reserved physical memory address corresponding to the physical memory address if the bad block information indicates that the given memory block is a bad block. In an example, the apparatus may be embodied as a memory device controller including a flash translation layer (FTL).

Apparatus, memory device controller and method of controlling a memory device

There is provided an apparatus for controlling a flash memory, which includes a memory for storing a plurality of flash translation layers; and a control block for, when an access is requested from outside, determining a pattern of the access, selecting one of the flash translation layers stored in the memory based on the determination result, and managing mapping data of the flash memory based on the selected flash translation layer.

Flash memory control devices that support multiple memory mapping schemes and methods of operating same

Memory systems and methods of controlling a flash memory are provided that execute one of a plurality of merge stages of an incremental merge operation responsive to receiving a command to the flash memory. Executing one of a plurality of merge stages may include receiving a command to the flash memory, determining whether the flash memory is executing an incremental merge operation and executing a next merge stage of the incremental merge operation if the flash memory is executing an incremental merge operation.

Incremental merge methods and memory systems using the same

A data management apparatus and method used in a system using one or more flash memories, which can deal with defective blocks in each of the flash memories using different methods depending on how the system manages data stored in each of the flash memories. The data management apparatus includes a device driver, which controls the operation of one or more flash memories, and a controller, which transfers data stored in a defective block of one of the flash memories to a predetermined block in the flash memory.
