US Patent 10535391 Semiconductor storage device

According to one embodiment, a semiconductor storage device includes: a first conductor coupled to a first end of a first cell; a second conductor which couples between a second end of the first cell and a first end of a second cell; a third conductor coupled to a second end of the second cell; a first current source being capable of coupling to the first cell via the first conductor; a second current source being capable of coupling to the second cell via the third conductor; a first sense amplifier configured to read data from the first cell based on a current flowing from the first current source to the first cell; and a second sense amplifier configured to read data from the second cell based on a current flowing from the second cell to the second current source.
