Transcribed Image Text:
The memory controller on a microprocessor employs a limited open page policy, keeping pages open for a fixed amount of time after each access. If no reference is made to the open page during that time, then it is closed (and ACTIVATE command is issued to the bank). Assume use of PC3-10600 DIMM with (9-9-9-24) timing. Assume memory reads only. a) How long (in DRAM memory cycles) will a memory reference take to complete if it's to an empty page (one that has been closed)? b) How long (in DRAM memory cycles) will a memory reference take to complete if it's a page hit (it's to an open page)? c) How long (in DRAM memory cycles) will a memory reference take to complete if it's a page miss (it's to a bank with an open page but it's not the page requested)?
