摘要： A controller controls a memory including first and second strings. The first and second strings configure first and second string groups, respectively. In each string group, a set of memory cell transistors each from each string configures a unit. The controller is configured to: sequentially write, in the first string group, data in first units to which serially-coupled memory cell transistors respectively belong; sequentially write, in the second string group, data in first units to which serially-coupled memory cell transistors respectively belong; and sequentially write, in the first string group, data in second units to which serially-coupled memory cell transistors respectively belong.
