Abstract
A method and apparatus for operating a memory device with wider difference in array and periphery voltage is presented. The memory device includes a bit line, a complementary bit line, a memory cell, a first pre-charge circuit, and a second pre-charge circuit. The memory cell, the first pre-charge circuit, and the second pre-charge circuit are coupled between the bit line and the complementary bit line. The first pre-charge circuit is configured to pre-charge the bit line and the complementary bit line to a first voltage level. The second pre-charge circuit is configured to pre-charge the bit line and the complementary bit line to a second voltage level that is different than the first voltage level. In some examples, two precharge circuits are configured to operate such that memory access is ensured to be static noise margin safe even under wider difference between two voltage levels.
