Memory device and method of operating the same

A memory device comprising:

• a plurality of memory cells configured to form a plurality of pages;
• a peripheral circuit configured to perform a first program operation on an adjacent page which is adjacent to a selected page among the plurality of pages and a second program operation on the selected page;
• and
• control logic configured to control the peripheral circuit to perform the first and the second program operations, wherein the control logic comprises:
• an address controller configured to generate a new address based on a target address on which the second program operation is to be performed;
• and
• a program controller configured to output an operating signal to perform the first and the second program operations based on the new address.

A method of operating a memory device comprising a plurality of memory cells configured to form a plurality of pages, the method comprising:

• successively receiving least significant bit (LSB) page data of an adjacent page which is adjacent to a selected page among the plurality of pages, center significant bit (CSB) page data, and most significant bit (MSB) page data of the selected page from a memory controller;
• performing a first program operation of programming the LSB page data of the adjacent page to the adjacent page;
• performing a recovery operation of reading LSB page data from the selected page, previously stored in the selected page;
• and
• performing a second program operation of programming, to the selected page, data generated by combining the LSB page data, the CSB page data, and the MSB page data of the selected page.
