Patent number: 9543033Abstract: According to one embodiment, a semiconductor memory device includes a memory cell array, a first circuit, and a second circuit. The first circuit executes program and read. The program is processing for changing a threshold voltage of a memory cell to a voltage according to data. The data includes first data of a bit and second data of a bit. The program of the second data is executed after the program of the first data. The read includes measuring the threshold voltage. The second circuit manipulates a flag in accordance with execution of the program of the second data. In a case where the second data is a target of the read, the second circuit refers to the flag. In a case where the flag indicates non-execution of the program of the second data, the second circuit aborts the measuring before the measuring of the threshold voltage is completed.Type: GrantFiled: March 1, 2016Date of Patent: January 10, 2017Assignee: Kabushiki Kaisha ToshibaInventors: Koichi Shinohara, Yoshikazu Takeyama

Patent number: 5896520Abstract: A virtual computer system of a multi-processor arrangement reduces the overhead of XPTLB processing. The processing of a PTLB (translation look-aside buffer processing) is controlled using IP dispatch information about virtual computers that is stored a hardware share area (HSA). A control unit (CU) has a group of bit-map BIM (broadcast IP mask) latches which correspond to the configured IP's and in which the IP dispatch information is set upon purging of a translation look-aside buffer. Through AND gate logic provided in the CU, whether or not an IP is to receive a PTLB request is determined on the basis of the information set in the BIM masks. Specifically, the AND gates compute the logical AND of each of the BIM masks with the control line of a XPTLB REQ from an IP being dispatched by a particular virtual computer.Type: GrantFiled: January 10, 1997Date of Patent: April 20, 1999Assignees: Hitachi, Ltd., Hitachi Information Technology Co., Ltd.Inventors: Takeshi Ohminato, Koichi Shinohara, Katsuichi Aoki
