Abstract:
1. A method of soft programming non-volatile memory, comprising: applying a first voltage to a set of word lines to enable pre-charging of a first set of non-volatile storage elements coupled to said set of word lines, said first voltage is different from a read pass voltage; while said first voltage is applied to each word line in said set of word lines, applying an inhibit voltage to a bit line for said first set of non-volatile storage elements to pre-charge a channel region of said first set of non-volatile storage elements; and while said inhibit voltage is applied to said bit line for said first set of non-volatile storage elements, applying a second voltage to said set of word lines to soft program a second set of non-volatile storage elements coupled to said set of word lines, said second voltage is higher than said first voltage.
