  • Patent number: 11532352
    Abstract: This disclosure describes a memory cell array with enhanced read sensing margin. The memory cell array includes a write port and a read port being connected through first and second data storage lines. The memory cell array further includes multiple word lines and bit lines arranged in rows and columns such that the read port is coupled to a read word line, a read bit line, and a virtual ground. The read port includes a first transistor coupled to at least the read bit line and the virtual ground, a second transistor coupled to at least the first data storage line and the first transistor, a third transistor coupled to at least the second data storage line and the read word line, and a fourth transistor coupled at least the first data storage line and the read word line.

  • Patent number: 11062766
    Abstract: A structure for an integrated circuit is disclosed for storing data. The integrated circuit includes a memory cell array of bit cells configured in a static random access memory (SRAM) architecture. The memory cell array is coupled to wordlines arranged in rows that control operations such as Read and Write operations. To enhance the read sensing margin of the SRAM configuration, the read port of a bit cell may include a wordline that drives two transistors (e.g., a PMOS and an NMOS transistor) to reduce data-dependent current leakage from a read bitline. An additional weak transistor keeper configuration may be used in the integrated circuit to compensate for current leakage from the read bitline. For example, a weak NMOS keeper that includes a sense amplifier, an inverter, and an NMOS connected to supply voltage VDD provides a path between the read bitline and VDD through the weak NMOS keeper.
