Publication number: 20240242765Abstract: A non-volatile memory device includes a memory cell array including memory cells coupled to word lines, a boost circuit that receives an external power supply voltage and generate a boosted voltage based on the external power supply voltage, a regulator that generates a regulated voltage based on the external power supply voltage, and a control logic that controls word line voltages provided to the word lines. The control logic performs plural program loops in a program operation for the memory cell array. The control logic provides an adjacent word line voltage to an adjacent word line that is adjacent to a selected word line. In a first section of the program loops, the control logic provides the regulated voltage as the adjacent word line voltage, and in a second section of the program loops, the control logic provides the boosted voltage as the adjacent word line voltage.Type: ApplicationFiled: October 20, 2023Publication date: July 18, 2024Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jayang Yoon, Chihyun Kim, Sangsoo Park, Junehong Park, Chiweon Yoon, Hyeongdo Choi

Patent number: 11079088Abstract: A lamp for a vehicle includes a light source part including a light source, a first lens part including a plurality of micro incidence lenses on which light generated from the light source part is incident, a second lens part including a plurality of micro emitting lenses each corresponding to each of the plurality of micro incidence lenses, and a shield part disposed between the first lens part and the second lens part. The shield part includes a plurality of shields configured to block some of the light incident from the plurality of micro incidence lenses on the plurality of micro emitting lenses. In particular, a light axis of the light source may be disposed to be spaced apart from a center line which connects centers of an incidence surface and an emitting surface of the first lens part in at least one of a side direction or a downward direction.Type: GrantFiled: March 18, 2020Date of Patent: August 3, 2021Assignee: SL CorporationInventors: Jongwoon Kim, Nakjung Choi, Hyeongdo Kim, Kihae Shin

Patent number: 10533724Abstract: Provided is a lamp for a vehicle capable of ensuring light efficiency to satisfy the performance requirements for light distribution. The lamp includes a light source portion, a first lens portion with a plurality of micro incident lenses onto which light generated by the light source portion is incident, a second lens portion with a plurality of micro exit lenses corresponding to the plurality of micro incident lenses, respectively, and a shielding portion with a plurality of shields that are disposed on rear focal points of the plurality of micro exit lenses to obstruct a portion of incident light. In particular, a focal distance of a micro exit lens among the plurality of micro exit lenses is shorter than a focal distance of a micro incident lens among the plurality of micro incident lenses, which corresponds to the micro exit lens.Type: GrantFiled: July 17, 2018Date of Patent: January 14, 2020Assignee: SL CorporationInventors: Jongwoon Kim, Nakjung Choi, Hyeongdo Kim, Kihae Shin

Patent number: 10274153Abstract: Provided is a lamp for a vehicle which is capable of forming a beam pattern having a cutoff line with a moderate sharpness. The lamp includes a light source portion, a first lens portion with a plurality of micro incident lenses, a second lens portion with a plurality of micro exit lenses corresponding to the plurality of micro incident lenses, respectively, and a shielding portion which includes a plurality of shields which form a plurality of illumination regions for forming a beam pattern by obstructing a portion of light which is incident onto each of the plurality of micro exit lenses. In particular, upper boundary lines of illumination regions formed by a first set of the plurality of shields are formed in positions different from those of upper boundary lines of illumination regions formed by a second set of the plurality of shields.Type: GrantFiled: July 17, 2018Date of Patent: April 30, 2019Assignee: SL CorporationInventors: Jongwoon Kim, Nakjung Choi, Hyeongdo Kim, Kihae Shin
