  • Patent number: 9508405
    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.

  • Patent number: 8780615
    Abstract: In a memory device, a bitline write voltage is applied to a first bitline. A wordline voltage is applied to a first wordline for writing data to a first memory cell connected to the first wordline and the first bitline. The first bitline and the second bitline are electrically connected for charge sharing between the first bitline and the second bitline. A predetermined time after electrically connecting the first bitline and the second bitline, the first and the second bitline are electrically disconnected and the bitline write voltage is applied to the second bitline. The wordline voltage is applied to a second wordline for writing data to a second memory cell connected to the second wordline and the second bitline.

  • Patent number: 8259486
    Abstract: A write boost circuit provides an automatic mode control for boost with different modalities with respect to the external supply voltage and also with respect to the extent of boost required at different process corners. The write boost circuit also takes care of the minimum boost provided to process corners with good writability where less boost is required. The boost is realized in terms of ground raising in the particular context and in general applicable to all other methods.

  • Publication number: 20100115385
    Abstract: An embodiment of the present disclosure relates to detection of data access element selection errors during data access in data storage arrays. An embodiment of the disclosure describes a system including a data storage array comprising a first and a second error identifier. The error identifiers generate an error signal in case multiple data access elements are selected or no data access element is selected, respectively. A system for detection of data-access-element-selection errors further comprises a common error-signal generator which provides an output when an error signal is generated by either of said error identifiers.
