BEDO DRAM (Burst Extended Data Output DRAM) is a type of dynamic random access memory (DRAM) that can send data back to the computer from one read operation at the same time it is reading in the address of the next data to be sent. In addition, after reading the address, it is able to send the data back in three successive clock cycles without clock coordination (that is, the three successive outputs seem to be sent from the RAM in a sudden burst. It works well with microprocessors that operate up to 66 MHz.
BEDO DRAM and various types of SDRAM are two recent RAM technologies that are being incorporated in newer computers.
