Method and apparatus for accessing memory with read error by changing comparison |
摘要 |
In response to a disagreement between a previously generated check code associated with previously programmed data bits and a more recently generated check code generated in response to a read command, the comparison process is changed, between i) a value representing accessed data and ii) a reference applied to such accesses to distinguish between logical levels. For example, the ratio of resistances characterizing input circuits of a sense amplifier and/or the read bias arrangement and/or a read reference of a memory integrated circuit is/are changed. |
