a memory page boundary. Method claims 12, 13, and 17 generally
correspond to apparatus claims 1, 2, and 6, respectively.
Claim 1 is reproduced below.
1. Memory control apparatus for use in a data processing
system having at least a requesting agent and said [sic]
replying agent electrically coupled together by a system
bus, the requesting agent requesting access to a memory on
the replying agent for storing and retrieving data therein
over the system bus, the apparatus comprising:
means, associated with a replying agent, for detecting
a request for initiating an access to a memory on the
replying agent, the request detecting means being coupled
to a system bus, and request being made over the system
bus by a requesting agent;
means, responsive to the request detecting means
detecting the request, for asserting a plurality of
memory address control signals for accessing a plurality
of times the memory on the replying agent, the control
signals comprising at least a row address strobe signal
associated with a memory row address and a column address
strobe signal associated with a memory column address;
and
means for detecting a completion of the access to the
memory, the completion detecting means being responsive
to an end of access control signal generated by the
requesting agent, the access completion detecting means
being coupled to the memory address control signal
asserting means for halting the operation thereof after
the end of access control signal is detected; and wherein
the memory address control signal asserting means
asserts the memory address control signals by asserting the
row address strobe in conjunction with a row address being
indicative of a page of data within the memory, and
thereafter asserts and deasserts a plurality of times the
column address strobe signal in conjunction with a plurality
of column addresses for performing a page mode type of
memory access.
