Abstract
A semiconductor integrated circuit device has a memory cell array including a plurality of pages and a page buffer. Each of the plurality of pages includes a user region and a page flag region in which page flag data indicative of a current state of a corresponding page is written. The page buffer includes a user page buffer section which temporarily holds the user data and a page flag page buffer section which temporarily holds the page flag data. The page flag data is recorded in the form of two levels in the non-volatile semiconductor memory cell arranged in the page flag region. The user data is recorded in the form of multilevel in the non-volatile semiconductor memory cell arranged in the user region.
