Multilevel DRAM (MLDRAM) increases the storage density of DRAMs by using more than two data signal levels in the storage cells. An operational 19200-cell MLDRAM in 1.8-V, 0.18-µm mixed-signal CMOS is described that allows 1, 1.5, 2, 2.25 and 2.5 bits-per-cell operation using 2, 3, 4, 5 and 6 data signal levels, respectively. The MLDRAM uses reference and(More)
Branch history table (BHT) prediction is a simple and effective method of predicting branch direction at run-time in a microprocessor. Unfortunately, this method suffers from performance limitations due to aliasing, which is when more than one branch uses a single entry in the branch history table. Theoretically, for programs that exhibit pseudo-random(More)
