<p><b>Halaman baru</b></p><div>'''Protokol MERSI''' adalah protokol koherensi [[tembolok]] dan koherensi memori yang digunakan pada arsitektur PowerPC G4. Protokol ini mendefinisikan lima keadaan (state) garis tembolok, yaitu ''Modified'' (M), ''Exclusive'' (E), ''Recent'' (R), ''Shared'' (S), dan ''Invalid'' (I).<br />
<br />
Keadaan M, E, S, dan I memiliki makna yang sama seperti pada protokol MESI. Keadaan R mirip dengan keadaan E karena menunjukkan bahwa hanya terdapat satu salinan data yang bersih dan valid dalam sistem. Perbedaannya terletak pada mekanisme transisi, di mana pada keadaan R prosesor harus terlebih dahulu meminta kepemilikan garis cache sebelum dapat memodifikasinya dan berpindah ke keadaan M. Pada protokol MESI dan MERSI, transisi dari keadaan E ke M dapat terjadi secara diam-diam (silent transition), tanpa komunikasi tambahan dengan subsistem koherensi.<br />
<br />
Untuk setiap pasangan cache, kombinasi keadaan yang diperbolehkan bagi suatu garis cache ditentukan oleh aturan koherensi yang diterapkan oleh protokol MERSI.<br />
