Method for writing data in a memory of a contactless transponder, and corresponding contactless transponder device

A contactless transponder device, comprising:

• a non-volatile static random access memory including memory points, wherein each memory point comprises a volatile memory cell and a non-volatile memory cell;
• a protocol processing circuit configured to receive data and to store the received data in the volatile memory cells;
• and
• a write processing circuit configured, at the end of reception and storage of the data, to record, in a single write cycle, the data from the volatile memory cells to the non-volatile memory cells of the respective memory points.

A method for writing data in a memory, the memory being a non-volatile static random access memory including memory points, wherein each memory point comprises a volatile memory cell and a non-volatile memory cell, the method comprising:

• receiving data;
• buffer storing of the received data in the volatile memory cells of the memory points;
• and
• in a single write cycle, recording the buffer stored data from the volatile memory cells of the memory points to the non-volatile memory cells of the memory points.

A memory device, comprising:

• a plurality of memory points, wherein each memory point comprises a volatile memory cell and a non-volatile memory cell;
• a first circuit configured to buffer store received data in the volatile memory cells;
• and
• a second circuit configured to transfer, in a single write cycle, the buffer stored data from the volatile memory cells to the non-volatile memory cells of the respective memory points.
