Abstract in simplified Chinese:本发明系将两种型式的指令间隙规格定义成第一和第二指令间隙规格。而分别将该第一指令间隙规格定义为授予给相同组合排上之前行指令与随后指令间的关系,而将该第二指令间隙规格定义为授予给不同组合排上之前行指令与随后指令间的关系。至于该第二指令间隙规格,由于前行指令与随后指令之间的标的组合排是不相同的,故能够在该前行指令之后的各行电路预充(例如某一共同I/O导线的预充)期间运行随后指令。因此,在施行该第二指令间隙规格的例子里实质上缩短了各指令间隙。除此之外,定义出成对的组合排当作各组合排对,并将前述第一和第二指令间隙规格应用在各组合排对上,以致该DRAM设备具有很小的芯片尺寸。

Abstract:
A method for allowing upstream channels having the same multiplexing type but different symbol rates or the same symbol rates but different multiplexing types to be transmitted on the same frequency band without interfering with each other. In particular, a method for allowing DOCSIS 1.0 TDMA only cable modems to coexist on a digital data delivery distributed system with DOCSIS 1.2 TDMA or SCDMA mode cable modems without the need for modification of the DOCSIS 1.0 cable modems or the need for the DOCSIS 1.0 modems to transmit on a different frequency. The method comprises: using a plurality of upstream channel descriptor messages transmitted from said central modem to said distributed modems to define a plurality of different upstream logical channels sharing the same frequency band, each said logical channel having either a different symbol rate but the same multiplexing type or the same multiplexing type but a different symbol rate, said upstream channel descriptor messages assigning each of said distributed modems to logical channels appropriate to the symbol rate and modulation type of said distributed modem; and, scheduling transmission bursts on each said logical channel by transmitting a bandwidth award and scheduling message for each logical channel each of which defines and controls which distributed modems on the logical channel to which the bandwidth award and scheduling message can transmit and when they can transmit, said bandwidth award and scheduling messages being coordinated by said central modem so that there is never any overlap in time between transmission bursts on different logical channels sharing the same frequency band.

Abstract:
Two types of command interval specifications are defined as first and second command interval specifications. The first command interval specifications is defined as the relationship between a preceding command and a following command that are issued for the same bank, while the second command interval specifications is defined as the relationship between a preceding command and a following command that are issued for different banks, respectively. As for the second command interval specification, since target banks are different between a preceding command and a following command, the following command is executed during the column circuits precharge after the preceding command. Therefore, in the case of the second command interval specification, a command interval is substantially shortened. In addition, pairs of banks are defined as bank pairs, and are applied the first and second command interval specifications, so that the DRAM device is small-sized.
