- I would like to know what would be the best (static?) ram to use in this
- situation...
-
- The memory configuration would be 16 elements wide (possibly expanded to
- 64) and 256 elements deep (possibly expanded to 4096). Each element or
- address would be 16 bits wide (or 12 bits if 16 bits is a problem).
-
- This memory block would 'grab' it's data from a 16 bit counter 'on the fly'
- (either directly or through a latched buffer). The counter is ticking over
- at 32 mhz (or higher?), and the 'grab' does not always correspond with the
- clock of the counter. The minimum time between 'grabs' would be 300 ns
- (800 ns more likely).
-
- Dual-ported-ness is not necessary.
- High-speed sequential readout will occur at the end of the memory input
- cycle (say 200 ns cycle time).
-
- E-mail or post suggestions... thanx!
