The MT46V64M8CV-5B:J is a version of Micron's MT46V64M8 64-megabit dynamic random access memory (DRAM) with a synchronous burst architecture. It has a 533-mega hertz (MHz) clock rate and a 5-nanosecond (ns) random-access time. The chip also has an 8-bit (8-bank) prefetch architecture and a very fast write cycle time of 5 nanoseconds. It also features four internal chip selects and a data mask register. The MT46V64M8CV-5B:J is a component of the industry-standard Small Outline (SOJ) packages with a lead pitch of 0.5mm. It is suitable for use in high-performance computer systems, digital editing systems, and other memory-intensive applications.
