Abstract

See full text

In certain aspects, a memory device includes an array of memory cells, an input/output (I/O) circuit, and I/O control logic coupled to the I/O circuit. The array of memory cells includes P groups of banks. P redundant banks are included in and shared by the P groups of banks. The I/O circuit is coupled to the P groups of banks and configured to direct P×N pieces of data to or from P×N working banks, respectively. The I/O control logic is configured to determine the P×N working banks from the P groups of banks based on bank fail information indicative of K failed main banks from the P groups of banks. The P×N working banks include K redundant banks of the P redundant banks. The I/O control logic is also configured to control the I/O circuit to direct P×N pieces of data to or from the P×N working banks, respectively.
