Apparatus and method for data communications between non-volatile memory devices and a memory controller

A system, comprising:

• a data path via which a plurality of transceivers is capable of transmitting data, the data path structured to carry the data transferred from one transceiver to another transceiver of the plurality of transceivers;
• and
• an interrupt path via which a plurality of interrupt circuits is capable of transmitting an interrupt signal, the interrupt path structured to carry the interrupt signal for interrupting access to the data path corresponding to the interrupt path,
• wherein a first interrupt circuit of the plurality of interrupt circuits generates a first interrupt signal that is transmitted through the interrupt path to interrupt access by the plurality of transceivers before a first transceiver corresponding to the first interrupt circuit transmits data via the data path,
• wherein the interrupt path comprises a first line structured to carry the first interrupt signal transmitted by the first transceiver and a second interrupt signal transmitted by a second transceiver different from the first transceiver at different times, wherein the first line is coupled to a switching circuit comprising a plurality of transistors serially connected between a power supply terminal for providing voltages and the first line.

A data communication method, comprising:

• receiving an activation signal for transmit or receive data through a first device of a plurality of devices via a data path via which the plurality of devices is capable of transmitting or receiving data;
• generating a first interrupt signal for interrupting access by the plurality of devices based on the activation signal, wherein the first interrupt signal is transmitted via an interrupt path via which the plurality of devices is capable of transmitting an interrupt signal, wherein the interrupt path comprises a first line structured to carry the first interrupt signal transmitted by the first device and a second interrupt signal transmitted by a second device different from the first device at different times, wherein the first line is coupled to a switching circuit comprising a plurality of transistors serially connected between a power supply terminal for providing voltages and the first line;
• activating a control signal to be applied to the first device based on the first interrupt signal and the activation signal;
• and
• transmitting or receiving the data through the first device based on the control signal.
