<p>A high-speed transparent refresh DRAM-based memory cell and architecture are disclosed. Each memory cell consists of 4 transistors configured to incorporate differential data storage (i.e., storing a true logic state and a complementary logic state), with each pair of transistors having a dual port configuration and forming one of a complementary pair of storage nodes for the memory cell. Each memory cell is coupled to 2 wordlines and 4 digit lines. Since the memory cell stores complementary data, and since a logic LOW state is rewritten to a given memory cell faster than a logic HIGH state is rewritten, the logic LOW state is rewritten and the complementary logic state is known to be a logic HIGH state. As a result, both the logic LOW and logic HIGH states are rewritten to the memory cell faster than independently writing a logic HIGH state.</p> |
