Abstract
A semiconductor storage device includes first, second, and third transistors, first, second, and third bit lines connected to the first, second, and third transistors, a word line connected to the first, second, and third transistors, and a control circuit configured to perform a program operation for writing data to the second and third transistors, including raising a first voltage applied to the first bit line at a first timing, raising a second voltage applied to the word line at a second timing, raising a third voltage applied to the second bit line at a third timing, raising a fourth voltage applied to the third bit line at a fourth timing, and lowering the first voltage at a fifth timing. The first voltage is raised to a first predetermined voltage, and each of the third and fourth voltages is raised to a second predetermined voltage smaller than the first predetermined voltage.
