<h1>RAM (Random Access Memory)</h1>
|
|
<h2>Overview</h2>
|
|
<p>The memory used in the Pokemon Mini is general purpose static ram.
|
|
It is high speed and there is no performance hit for accessing it other
|
|
than the instruction processing speed. The biggest problem with the
|
|
system is that the ram is small, and also shared with the <a href="PM_PRC.html" title="PM PRC">picture rendering chip</a>. Sections of this memory can be disabled, but up to 1248 bytes of 4k can be re-purposed for video. </p>
|
|
<p>General purpose memory is considered unused and is safe for all use at any time. Disabling various parts of the <a href="PM_PRC.html" title="PM PRC">picture rendering chip</a> can free up additional memory. </p>
|
