A 5.0Gbps/pin packet-based DRAM with low latency receiver and process insensitive PLL

A 2.0V, 256Mbit packet-based DRAM with bandwidth of 10GB/s (5.0Gbps × 16pin) was fabricated. To have high data bandwidth and stable clock generation, high performance input receiver and process insensitive PLL bias scheme were used. To increase the write speed of the cell array, write without 10 pre-charge scheme was employed. The power consumption and area of the chip are 2.4W and 7.2×10.2mm² respectively.
