a direct access RAM which is a volatile storage whose content requires periodic refreshment. Unlike other types of memory devices, dynamic-RAM uses only one tiny transistor per memory cell. A binary state is represented by the presence or absence of an electric charge in each storage cell., dynamic memory - one which needs to be periodically refreshed, ie read and written every 2ms or so, as stored charge tends to leak, random access memory - a computer memory which can be read from and written to by the programmer. It is usually made on a chip. Each memory location can be identified by an address. Unlike data on magnetic tape or disks, data in random access memory is volatile. The time required for reading out data is independent of its location in the memory., salvestise pideva regenereerimisega pooljuhtmälu
