摘要:
Methods and apparatus provide for writing data into and reading data from an anti-parallel storage circuit of an SRAM memory cell via a true bit line (BLT) and a complementary bit line (BLC); and preventing the complementary bit line (BLC) from substantially dropping from a pre-charge, logic high voltage level during operations in which a logic low level is written into the anti-parallel storage circuit.
