DOUBLE FETCH FOR LONG BURST LENGTH MEMORY DATA TRANSFER
For a memory device where a data fetch accesses N/2 data bits, and the memory device is to transfer N bits over a data burst of length M in response to a read command, the memory device accesses the same bank twice to access the N bits. Instead of accessing N/2 bits from 5 two different banks, the m...

Zusammenfassung: | For a memory device where a data fetch accesses N/2 data bits, and the memory device is to transfer N bits over a data burst of length M in response to a read command, the memory device accesses the same bank twice to access the N bits. Instead of accessing N/2 bits from 5 two different banks, the memory device accesses a single bank twice. The memory device can control the timing of the data transfer to enable sending all N data bits to the memory controller for the read command. The memory device can send data as a first transfer of burst length M/2 of a first N/2 data bit portion and a second transfer of burst length M/2 of a second N/2 data bit portion. 10 |
