摘要： A first operation identifier is assigned to a current operation directed to a memory component, the first operation identifier having a first entry in a first data structure that associates the first operation identifier with a first buffer identifier. It is determined whether the current operation collides with a prior operation assigned a second operation identifier, the second operation identifier having a second entry in the first data structure that associates the second operation identifier with a second buffer identifier. A latest flag is updated to indicate that the first entry is a latest operation directed to an address (1) in response to determining that the current operation collides with the prior operation and that the current and prior operations are read operations, or (2) in response to determining to determining that the current operation does not collide with a prior operation.

摘要： A first operation identifier is assigned to a first operation directed to a memory component, the first operation identifier having an entry in a first data structure that associates the first operation identifier with a first plurality of buffer identifiers. It is determined whether the first operation collides with a prior operation assigned a second operation identifier, the second operation identifier having an entry in the first data structure that associates the second operation identifier with a second plurality of buffer identifiers. It is determined whether the first operation is a read or a write operation. In response to determining that the first operation collides with the prior operation and that the first operation is a read operation, the first plurality of buffer identifiers are updated with a buffer identifier included in the second plurality of buffer identifiers.

摘要： A request to read data from a location associated with a memory component is received. The request is assigned a first tag, the first tag having a first identifier of a first buffer to store data read from the location. The request to read data is determined to collide with an earlier request to write data to the location. The earlier request is assigned a second tag, the second tag having a second identifier of a second buffer to store data to write to the location. An attempt to lock the second tag and the second buffer for the request to read data is made. The request to read data is fulfilled from the second buffer in response to a successful attempt to lock the second tag and the second buffer.

摘要： A first operation identifier is assigned to a first operation directed to a memory component, the first operation identifier having an entry in a first data structure that associates the first operation identifier with a first plurality of buffer identifiers. It is determined whether the first operation collides with a prior operation assigned a second operation identifier, the second operation identifier having an entry in the first data structure that associates the second operation identifier with a second plurality of buffer identifiers. It is determined whether the first operation is a read or a write operation. In response to determining that the first operation collides with the prior operation and that the first operation is a read operation, the first plurality of buffer identifiers are updated with a buffer identifier included in the second plurality of buffer identifiers.
