Abstract
A high access rate flash control provided for accessing more than one flash memory chip having different access timing specifications is disclosed. The controller comprises a read/write(R/W) pulse generator, a R/W delay chain circuit, a sampling delay chain circuit, a bi-directional feedback pad (PAD), a data bus sampler, and a second pad (PAD). In an embodiment, the flash controller using a fix clock to generate synchronized Read/Write pulse which is then appropriated adjusted by the R/W delay chain circuit to provide optimum R/W control signal. The adjusted R/W signal is than outputted by a bi-directional pad to flash memory chips. With the external signal feedback function, the bi-directional pad has associated with the sampling delay chain, the time latency due to pads can be eliminated nearly. Thus, the flash controller can approach high rate to access flash chips.
