Publication number: 20240096413Abstract: A control circuit of a semiconductor memory device performs a write operation on a memory cell transistor of the semiconductor memory device by performing a first pulse application operation of lowering a threshold voltage of the memory cell transistor, a precharge operation, and then a second pulse application operation. In the precharge operation, in a state in which first and second select transistors connected to the memory cell transistor are turned on, a bit line connected to the memory cell transistor is charged by applying a ground voltage to a word line connected to a gate of the memory cell transistor and applying a voltage higher than the ground voltage to a source line. In the second pulse application operation, in a state in which the first select transistor is turned on and the second select transistor is turned off, a program voltage is applied to the word line.Type: ApplicationFiled: March 2, 2023Publication date: March 21, 2024Inventors: Natsuki SAKAGUCHI, Takashi MAEDA, Rieko FUNATSUKI, Hidehiro SHIGA

Patent number: 10248511Abstract: A primary storage system is equipped with a local storage subsystem having a mirror volume of a volume in a primary storage subsystem, and a remote storage subsystem having a mirror volume of the volume in the primary storage subsystem at a secondary site. When storing a write data from a host to a volume, the primary storage subsystem determines an SEQ# to be stored in a journal corresponding to the write request, creates a journal including the relevant SEQ# and a replica of the write data, and transmits the relevant SEQ# to the local storage subsystem, which creates a journal including the relevant SEQ# and stores it in its own journal volume. But when creation of the journal including the relevant SEQ# is stopped, the local storage subsystem creates a dummy journal including the relevant SEQ# but not including the write data.Type: GrantFiled: November 26, 2014Date of Patent: April 2, 2019Assignee: Hitachi, Ltd.Inventors: Ryunosuke Kamimoto, Hideo Saito, Azusa Jin, Keishi Tamura, Takahiko Takeda, Takashi Sakaguchi, Hiroyuki Morimoto

Patent number: 9239845Abstract: A backup copy from a first data volume to a second data volume is executed according to either a synchronous mode, in which write data is copied from the first data volume to the second data volume in synchronous with a write request, or an asynchronous mode, in which journal data of a first storage apparatus is reflected on the second data volume in asynchronous with the write request. A second storage apparatus acquires secondary load information representing its own load status, and transmits the information to the first storage apparatus. The first storage apparatus acquires primary load information representing its own load status, determines switching between the modes based on the secondary load information, the primary load information and mode information, and transmits determination information representing determination results to the second storage apparatus.Type: GrantFiled: December 24, 2013Date of Patent: January 19, 2016Assignee: HITACHI, LTD.Inventors: Takashi Sakaguchi, Takamasa Sato, Kensuke Narita, Yosuke Katoh
