I am searching, with no success, in multiple categories of the external memory IC market for a chip that can do the following:
- Store 1MB of data of 16-bit data
- This data is stored at specific addresses
- When I put it into read mode it uses it's 16 output pins to display it's 16-bit values in memory i.e. if the value at address 0x0000 was 0000 0000 0001 0010 this value would be on the pins in +V/0V.
- When I increment a pin with a clock it will change to address 0x0001 and display that value on it's pins.
- Preferably has unlimited write cycles like SRAM.
- Data can be volatile
I can find sram which matches the address on it's input pins and then displays the value at that address to it's output pins. but it won't clock automatically to increment and requires specific reconfiguring of the address pins.
An example that is close is the CY62256NLL-70ZRXIT. but it will not auto increment its address with an external input on its display pins.
Anyone got any suggestions? I suspect it's maybe a type of ram that I am not aware of.
