Abstract
An octo mode program and erase operation method to reduce test time in a non-volatile memory device. M/8 word lines corresponding to an octo row, among M word lines, are simultaneously selected, and a write voltage is applied to memory cells connected to M/8 word lines corresponding to the octo row. A voltage that is different from the write voltage is applied to memory cells connected to the rest of word lines, except for M/8 word lines corresponding to the octo row, when the octo signal is applied to an address decoder.
