Managing write-to-read turnarounds in an early read after write memory
system is presented. Memory controller logic identifies a write
operation's bank set, allows a different bank set read operation to issue
prior to the write operation's completion, and allows a same bank set
read operation to issue once the write operation completes. The memory
controller includes operation counter logic, operation selection logic,
operation acceptance logic, command formatting logic, and memory
interface logic. The operation counter logic receives
new-operation-related signals from the operation acceptance logic and, in
turn, provides signals to the operation selection logic and the operation
acceptance logic as to when to issue a read operation that corresponds to
either an even DRAM bank or an odd DRAM bank.
