What is BEDO ?
| Burst Extended Data Out |
|
BEDO Burst Extended Data Out DRAM (Burst EDO, BEDO) A variant on EDO DRAM in which read or write cycles are batched in bursts of four. The bursts wrap around on a four byte boundary which means only the two least significant bits of the CAS address get modified internally to produce each address of the burst sequence. Consequently, Burst EDO bus speeds will range from 40MHz to 66 MHz, well above the 33MHz bus speeds can be accomplished using Fast Page Mode or EDO DRAM. Burst EDO was introduced sometime before May 1995. 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. |
