Abstract
A non-volatile semiconductor device and a method for controlling the same are disclosed, which can increase a read efficiency of the non-volatile semiconductor device using the Low Power Double Data Rate (LPDDR) 2 specifications. The non-volatile semiconductor device includes a decoder configured to output a plurality of active control signals by decoding an active address and an active signal, and a plurality of active controls configured to be controlled by the plurality of active control signals and a plurality of active reset signals so as to generate a plurality of active enable signals that are independently activated.
Claims21
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;
- and
- 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 to control active states of a plurality of partitions of a cell array.
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 through the transmission line.
A method for controlling a non-volatile semiconductor device, the method comprising:
- outputting a first active control signal and a second active control signal by decoding an active address and an active signal;
- activating a first active enable signal in response to the first active control signal so as to activate a first bank;
- and
- activating a second active enable signal in response to the second active control signal to activate a second bank while the first bank is activated.
