Abstract:
A bad block of memory cells is quickly detected and removed from further programming during concurrent multi-block program operations, to minimize a threshold voltage upshift in a good block. A difference in program speeds between the blocks can be quickly detected by detecting when the memory cells in each block pass a verify test, such as a verify test of a lowest programmed data state. If a first block passes the verify test at a reference program loop, a determination is made as to whether a second block passes the verify test within a specified number of additional program loops. If the second block meets this criterion, the program operation can continue for both blocks. However, if the second block does not meet this criterion, the program operation is terminated for the second block by isolating it from subsequent program and verify signals.

Claim (Index 12):
The apparatus of  claim 1 , wherein:\n the memory cells in the first block comprise memory cells with a first assigned programmed data state and memory cells with a second assigned programmed data state which is higher than the first assigned programmed data state; the first verify test is for the first assigned programmed data state; the predetermined number of memory cells in the first block comprise memory cells with the second assigned programmed data state; and during program voltages applied to the first block of memory cells in the concurrent program operations, the control circuit is configured to apply a slowdown measure for the memory cells with the first assigned programmed data state but not for the memory cells with the second assigned programmed data state before the detection is made, and to remove the slowdown measure for the memory cells with the first assigned programmed data state after the detection is made.
