摘要:
In some embodiments, a chip includes a request queue to include write requests, and scheduling circuitry to schedule commands including commands in response to the write requests. The chip also includes mode selection circuitry to monitor the request queue and in response thereto to select a first or a second mode for the scheduling circuitry, wherein in the first mode the scheduling circuitry schedules certain commands as separate single commands and in the second mode the scheduling circuitry schedules consolidated commands to represent more than one separate single command. Other embodiments are described.

In some embodiments, a chip includes a link interface, monitoring circuitry to provide an activity indicator that is indicative of activity of the chip, and scheduling circuitry to schedule commands. The chip also includes mode selection circuitry to select a first mode or a second mode for the scheduling circuitry depending on the activity indicator, wherein in the first mode the scheduling circuitry schedules certain commands as separate single commands and in the second mode the scheduling circuitry schedules at least one consolidated command to represent more than one of the separate single commands. Other embodiments are described.
摘要:
Apparatus and method to select write transactions and to selectively mark a write transaction with a page closing hint to cause the page in a memory device to which the write transaction is directed to be closed immediately after the write transaction is carried out if no other write transaction is found in a buffer of pending write transactions that is directed to the same rank, bank and page to minimize incidents of incurring lengthy page miss delays.
摘要:
A method and an apparatus to process read data return has been disclosed. In one embodiment, the method includes packing a cache line of each of a number of read data returns into one or more packets, splitting each of the one or more packets into a plurality of flits, and interleaving the plurality of flits of each of the plurality of read data returns. Other embodiments are described and claimed.
摘要:
Memory device having banks of memory cells organized into two groups of banks that share control circuitry and a data buffer to provide an interface to a memory bus, but which are independently operable enough to support unrelated transactions with each group, and can be used to stagger read operations with shortened burst transfers so as to minimize dead time on a memory bus.
摘要:
A device, method, and system are disclosed. In one embodiment, the device comprises one or more graphics local memory channels, one or more system memory channels, and a graphics processor operable to access the one or more graphics local memory channels and the one or more system memory channels in an interleaving manner.
摘要:
In some embodiments, a method, apparatus and system for posted write buffer for memory with unidirectional full duplex interface are presented. In this regard, a buffer agent is introduced to send data to a posted write buffer and to send an independent indication to the memory to write the data to an address. Other embodiments are also disclosed and claimed.
摘要:
In some embodiments, a chip includes a memory core, control circuitry, and first ports, second ports, and third ports. The first ports are to only receive signals, the second ports are to only provide signals, and the control circuitry is to control whether the third ports are to only receive signals or only provide signals. Other embodiments are described and claimed.
摘要:
In some embodiments, data may be transferred from a first memory agent to a second memory agent in a first format having a first width, and at least a critical portion of the data maybe transferred from the second memory agent back to the first memory agent in a second format having a second width, where the critical portion is included in a first frame. The critical portion may include a cacheline mapped over a memory device rank. Other embodiments are described and claimed.
摘要:
In some embodiments, a system includes a memory controller chip, memory chips on a first substrate, and a module connector. A first group of conductors is included to provide read data signals from at least some of the memory chips to the memory controller chip, and a second group of conductors to provide read data signals from the connector to the memory controller chip. The module connector may receive a continuity card or memory module. Other embodiments are described.
