Abstract: A semiconductor memory device includes a memory array, a setting unit and a control unit. The memory array consists of non-volatile memory cells. The setting unit set a page address of the memory array which is initially read out at startup. The control unit performs an internal sequence to read out the page address from the setting unit at startup and, according to the read-out page address, transmits page data corresponding to the read-out page address from the memory array to a page buffer.

Abstract: A semiconductor storage apparatus and an error checking and correction (ECC) related information reading method, which can output various information related to pages that have been error-corrected during a continuous reading operation, are provided. A NAND flash memory includes a memory cell array, a continuous reading component, an ECC related information memory part, and an output component. The continuous reading component continuously reads pages of the memory cell array. The ECC related information memory part stores page addresses of all of the pages that have been error-corrected by an ECC circuit regarding the pages continuously read by the continuous reading component. The output component outputs page addresses stored in the ECC related information memory part in response to a read command after the continuous reading operation.

Abstract: A semiconductor memory device is provided. The semiconductor memory device includes a memory cell array, a page-reading portion which selects a page of the memory cell array, reads data of the selected page, and transmits the read data to a data-holding portion, and a control portion which controls continuous reading of pages. When a command related to termination of the continuous reading is input, the control portion terminates the continuous reading. When the command related to the termination of the continuous reading is not input, the continuous reading terminates. During a period in which the continuous reading is performed continuously, even if a chip selection signal is toggled, the continuous reading can be performed continuously without inputting a page-data read command.

Abstract: A semiconductor memory device, a flash memory and a continuous reading method thereof are provided for achieving a continuous reading of pages in high speed. A flash memory of the invention includes a memory cell array; a page reading element, which selects a page of the memory cell array and reads out data of the selected page to a page buffer/sense circuit; a page information storage element, which stores page information related to a range of a continuous reading; and a control element, which controls the continuous reading of the page. The control element determines whether to resume the continuous reading according to the page information. When it is determined to resume the continuous reading, the continuous reading can still be performed without a page data read command and a page address being inputted even if a chip select signal is toggled.

Abstract: The invention provides a flash memory which may effectively protect information with a high security level. A flash memory includes a setting part. When the setting part is inputted a specific command, the setting part sets up specific address information to a nonvolatile configuration register, and sets up specific data in a hidden storage region. The flash memory also includes: a comparing part, which compares inputted address information and the specific address information during a reading operation; and a control part, which reads specific data set in the storage region and erases a specific address when two address information are consistent, and reads data stored in a memory array according to the inputted address information when two address information are inconsistent.

Abstract: A flash memory that improves the reliability of data stored in a memory cell array is provided in the disclosure. A wear leveling method of the flash memory of the disclosure includes the following operation. The memory cell array includes multiple sectors, the method includes the following operation. A region is set for storing a first flag and a second flag in each sector of multiple sectors of the memory cell array. The first flag indicates whether bit correction has occurred, and the second flag indicates whether specific data is stored. The second flag of a source sector among the sectors in which the specific data is stored is set. The specific data is written to a new sector among the sectors in which the first flag is in a reset state, and the second flag of the new sector is set.
