Semiconductor memory device and memory card

A memory card including a semiconductor memory device, wherein the semiconductor memory device comprises:

• a memory cell array including a plurality of memory blocks, each memory block including a plurality of memory cells arranged in a matrix and the memory cell array including a plurality of first select gate transistors to select one or more memory cells;
• a select gate line configured to input a control signal which controls continuity of the first select gate transistor to a gate of the first select gate transistor, the select gate line being shared between two adjacent memory blocks;
• and
• a row select circuit configured to select a memory block of a row designated by an input address signal, and
• the row select circuit comprises:
• only one transfer transistor provided between the select gate line and a non-select signal line to which a non-select signal is supplied, the non-select signal being the control signal indicating non-selection;
• and
• a select gate control circuit configured to bring the transfer transistor into conduction to supply the non-select signal to the select gate line when both the two adjacent memory blocks are not selected.
