Abstract:
A non-volatile semiconductor storage device includes a memory cell array and a control circuit configured to control a data write operation for the memory cell array in a first or second write mode in response to a write command sequence. In the first write mode, the control circuit performs a first write operation, which includes an operation in which one or more bit lines are charged according to write data and an operation in which a write voltage is applied to a selected word line according to address data included in the write command sequence. In the second write mode, the control circuit performs a second write operation, which includes the operation in which the one or more bit lines are charged according to the write data and does not include the operation in which the write voltage is applied to the selected word line.

Claim (Index 9):
A non-volatile semiconductor storage device comprising:\n a memory cell array that includes a plurality of non-volatile memory cells that are connected to a plurality of bit lines and a plurality of word lines; and a control circuit configured to write m (m is an integer of 2 or more) pages of data in a first non-volatile memory cell group connected to a selected word line of the plurality of word lines, by setting the non-volatile memory cells of the first non-volatile memory cell group to be in any one of 2 m  states of threshold voltage levels that are different from one another, wherein, in response to a first command, the control circuit applies a first read voltage corresponding to a first state of the 2 m  states to the selected word line, and reads first data from the non-volatile memory cells of the first non-volatile memory cell group, applies a second read voltage corresponding to a second state of which a threshold voltage level is higher than that of the first state, to the selected word line, and reads second data from the non-volatile memory cells of the first non-volatile memory cell group, applies a third read voltage which corresponds to the first state and is higher than the first read voltage to the selected word line, and reads third data from the non-volatile memory cells of the first non-volatile memory cell group, applies a fourth read voltage which corresponds to the second state and is higher than the second read voltage to the selected word line, and reads fourth data from the non-volatile memory cells of the first non-volatile memory cell group, and counts a first number of turned-on non-volatile memory cells that changed based on the first data and the third data and counts a second number of turned-on non-volatile memory cells that changed based on the second and the fourth data, and wherein the selected word line and the plurality of bit lines are discharged to a reference voltage and voltages of the plurality of bit lines are raised to a pre-charge voltage from the reference voltage during a transition from the read operation of the second data to the read operation of the third data.
