TN-41-02: DDR3 ZQ Calibration

Technical Note DDR3 ZQ Calibration Introduction For more robust system operation, the DDR3 SDRAM driver design has been enhanced with reduced capacitance, dynamic on-die termination (ODT), and a new calibration scheme. The capacitance reduction comes from the use of a new “merged” driver. With

TN-ED-03: GDDR6: The Next-Generation Graphics DRAM

From the figure above it becomes apparent that the three GDDR standards have many similarities. In fact, taking GDDR5 as the parent GDDR standard, only select items have been modified from the migration of GDDR5 to GDDR5X and GDDR6 to allow as smooth a transition as possible to each next-generation standard.

Hybrid Memory Cube HMC Gen2 - Micron Technology

Hybrid Memory Cube (HMC) is a single package con-taining four DRAM die and one logic die, all stacked together using through-silicon via (TSV) technology. Within each cube, memory is organized vertically— portions of each memory die are combined with the corresponding portions of the other memory die in the stack.

right memory design methodology can be critical to a project’s success. While DDR3 SDRAM was targeted for use on modules, it can easily be adapted for point-to-point ap-plications. DDR3 is an evolutionary transition from DDR2. DDR3 point-to-point systems are simi-lar to DDR2 point-to-point systems; both require similar design principles. But ...

The read-out of the 1T DRAM cell is destructive; read and refresh operations are necessary for correct operation. Unlike 3T cell, 1T cell requires presence of an extra capacitance that must be explicitly included in the design. When writing a “1” into a DRAM cell, a threshold voltage is lost.
