Abstract:
1. A non-volatile semiconductor device, comprising: a decoder configured to output a plurality of active control signals by decoding an active address and an active signal; a plurality of active controllers configured to generate a plurality of active enable signals in response to the plurality of active control signals and a plurality of active reset signals, the plurality of active enable signals being independently activated; a plurality of banks, wherein active states of the banks are selectively controlled by the plurality of active enable signals; a plurality of sense-amplifiers configured to sense and amplify data read out of the banks and transmit the amplified data to a transmission line; and a row data buffer configured to buffer the amplified data transmitted from the transmission line to compensate for a difference between a programming operation time and a read operation time of the plurality of sense-amplifiers, wherein a second sense-amplifier corresponding to a second bank performs a sensing operation in response to a corresponding active enable signal during a predetermined time in which a first sense-amplifier corresponding to a first bank transmits sensed data to the transmission line, and wherein, during a predetermined time in which the second sense-amplifier corresponding to the second bank transmits sensed data to the transmission line, a read operation for the first bank is performed.
