Assignee: KIOXIA CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A semiconductor memory device comprising
a plastic package including:
an inductor;
a first memory chip including a booster circuit that boosts a voltage from a first voltage to a second voltage using the inductor; and
a second memory chip having a terminal supplied with the second voltage from the first memory chip, wherein
the first and second memory chips perform data writing by the second voltage, wherein
the booster circuit includes:
a switching element having one end connected to the inductor and another end having a ground potential;
a rectifier circuit that is connected to the inductor and rectifies an output voltage of the switching element; and
a control circuit that performs switching control of turning on or off the switching element according to an output voltage of the rectifier circuit, and
the plastic package includes a capacitor having one end connected to an output node of the rectifier circuit and another end having a potential of the ground potential.
