  • Patent number: 7706172
    Abstract: A SRAM memory cell including two inverters and a plurality of switches is provided. The SRAM cell is manufactured in a technology offering N/P shunt capabilities and the inputs of the inverters are connected to at least one pair of bit lines (BLa, BLa/; BLb, BLb/) via two of the switches. The switches are controlled by a signal word line (WLa, WLb). Each inverter includes a first transistor (MN0, MN1) of a first conductivity type and a second transistor (MP0, MP1) of a second conductivity type. Each switch includes at least a third transistor (MN2, MN3) of the first conductivity type, characterized in that the two transistors (MP0, MP1) of the second conductivity type in the inverters are arranged in two opposite end regions of the memory cell, respectively.

  • Patent number: 6879511
    Abstract: A SRAM on an SOI substrate comprising a network of rows and columns of 6T memory cells with two inverters and two switch transistors, each cell being connected to two bit lines and to one of the word lines. Each memory cell comprises two first regions of the first conductivity type, each first region comprising the drains or the sources of first and third transistors, and being in contact with a second region of the second conductivity type comprising the drain or the source of a second transistor, the first and second regions being short-circuited by a conductive material, the conductive tracks of the first level taking part in the interconnections between the inverters, and in the interconnections between the switch transistors and the word line being parallel to the bit lines.
