The memory device includes a content addressable memory (CAM) block including a plurality of pages, peripheral circuits configured to perform a CAM data read operation to read a CAM data comprising a plurality of check data each indicating whether bad block information is included in a region of the CAM data from a page sequentially selected among the plurality of pages, a CAM data read controller configured to perform a CAM data load operation to receive the CAM data from the peripheral circuits and output the CAM data to an external memory controller, and stop the CAM data load operation based on at least one check data among the plurality of check data included in the CAM data.

Memory device, memory system including memory device, and method of operating memory system

A semiconductor memory device includes a column address generation circuit suitable for generating contents addressable memory (CAM) column addresses for duplicated CAM data, a column selection circuit suitable for allocating columns to the duplicated CAM data according to the CAM column addresses, and a plurality of page buffer units, each unit being coupled to a corresponding memory group through the allocated columns, and suitable for storing the duplicated CAM data in the memory groups through the allocated columns. The allocated columns are of arranged sequentially within each memory group in a circular order, and a part of the CAM column addresses represent columns which are physically apart by a predetermined number of columns within a memory group.

Semiconductor memory device and operating method thereof

A fouling free clean EGR system for a diesel-gasoline dual fuel powered engine allows re-circulation of an exhaust gas of a certain cylinder among a plurality of cylinders. The fouling free clean exhaust gas recirculation (EGR) system for a diesel-gasoline dual fuel powered engine in which gasoline and air are pre-mixed and supplied to cylinders and then a diesel fuel is injected and combusted together comprises a directly-exhaust cylinder of which an exhaust valve of the cylinder is connected to an exhaust manifold directly connected to a after treatment device; and an EGR cylinder of which an exhaust valve of the cylinder is connected to an EGR line and which supplies the EGR gas to the diesel-gasoline dual fuel powered engine.

Diesel-gasoline dual fuel powered engine with fouling free clean EGR system

A method of controlling combustion of an engine improves unstable ignition and knocking which may be generated in an engine to which a diesel-gasoline mixed combustion mode and a gasoline mixed combustion mode are applied to low load and high load driving zones. The method includes: determining a combustion mode according to a current driving state of the engine; determining a compression ratio corresponding to the combustion mode; controlling a variable compression ratio device to control a compression ratio of a cylinder; determining whether the combustion state of the engine obtained during the combustion after the control to the compression ratio satisfies a set condition; and performing a compression ratio compensation such that the combustion state of the engine satisfies the set condition with taking a combustion pressure sensor signal as a feedback signal when the set condition is not satisfied.

Method and apparatus for controlling combustion of engine having mixed combustion mode

A diesel engine piston having a combustion chamber may include a profile surface that protrudes toward a center axis of the combustion chamber from an inner wall thereof and includes a protrusion on the inner wall, the protrusion extending from the inner wall with a predetermined length, wherein the protrusion divides a spray fuel, which may be sprayed and atomized onto the protrusion, into a fuel flow at an upper portion of the combustion chamber and a fuel flow at a lower portion of the combustion chamber, respectively.

Diesel engine piston

A diesel-gasoline dual fuel powered combustion engine system is provided with spark-assisted fouling free EGR system in which gasoline and air are homogeneously combined and supplied to cylinders and then a diesel fuel is injected and combusted together. The system may include: a plurality of cylinders each having a fuel injector; and an exhaust line through which flows an exhaust gas discharged as a fuel from each cylinder is combusted; wherein gasoline fuel combustion type is adapted to one or more cylinder of the plurality of the cylinders, and diesel-gasoline fuel pre-mixed combustion type is adapted to the other cylinders.
