Lpc2000

I assumed you wired the RAMs as follows:

RAM:OE <- LPC:OE
RAM:A0 <- LPC:A1 (this is important, otherwise you can use only half of
the ram)
RAM:A1 <- LPC:A2 (etc.)
RAM:WR <- LPC:BLSn (needed for byte writes)

see also figure 8 on page 45 of the LPC2214 User Manual  (May 03, 2004).

The BCFG configuration (assuming CCLK = 58.9824 MHz)

WST1 >= 55 ns (3.24 * CCLK cycle) -> WST1 = 3
WST2 >= 45 ns (2.65 * CCLK cycle) -> WST2 = 2
IDCY >= 20 ns (1.10 * CCLK cycle) -> IDCY = 1
RBLE = 1 (you need the BLS lines)
WP = 0
BM = 0
MW = 1 (16 bit = 2 x 8 bit devices)

These are the minimum values you can use, but for testing I would use
the maximum values allowed by the LPC2214 to see if the RAM is wired and
soldered correctly.
