The Micron MT46V32M16P-5B IT:J is a 512 Mbit DDR SDRAM organized as 32M x 16 bits. It runs on a 200 MHz clock, delivering a 700 ps access time on a parallel interface.
The 200 MHz clock rate is the core timing reference for the DDR interface. The 700 ps access time (tAC) is the maximum time from the clock edge to valid data on the DQ pins.
That includes outdoor telecom cabinets and factory-floor PLC racks.
