Additional Details

The MSM514100D-60JS-7DR1 uses a standard asynchronous DRAM interface, similar to other DRAMs of its era. The 60ns access time defines the time required to output valid data after an address is applied to the memory. Refresh cycles are essential to prevent data loss, due to the nature of charge storage in DRAM cells. Full details on timings, power consumption, and operating requirements can be found in the official OKI/Metcal datasheet for the MSM514100D-60JS-7DR1.
