MT49H16M18FM-25:B

The Micron Technology MT49H16M18FM-25:B is a high-performance DRAM component with a memory size of 288Mbit. It features a parallel interface and operates as volatile memory.

Key electrical specifications include a clock frequency of 400 MHz and an access time of 20 ns. The operating voltage range is between 1.7V and 1.9V. The component supports a 533 MHz DDR operation with a peak bandwidth of 38.4 Gb/s. It is organized as 16M x 18 and utilizes an SRAM-type interface.

This DRAM is housed in a 144-TFBGA package and is designed for surface mount applications. The operating temperature range is 0°C to 95°C (TC). The datasheet also indicates features such as differential input clocks, an on-die DLL, and programmable read latency.

Additional specifications from the datasheet include 8 internal banks for concurrent operation, a reduced cycle time of 15 ns at 533 MHz, and support for data masks for WRITE commands. The I/O standard is HSTL, with matched impedance outputs between 25–60 Ω. It operates with VEXT at 2.5V, VDD at 1.8V, and VDDQ I/O at 1.5V or 1.8V.
