More pinouts for different sizes of 62* SRAM's

Some extra pinouts for SRAMs: 62256 is identical except for the !CS2 input and NC becoming address lines. This is to make address expansion of a board design almost trivial using inverters as half of an address decoder (other half is !CS input). CY62256 SRAM (28 pins, 1-14,28-15) Note that the Ax and Dx line order doesn't really matter. A5 +5V
A6 !WE
A7 A4
A8 A3
A9 A2
A10 A1
A11 !OE
A12 A0
A13 !CS
A14 D7
D0 D6
D1 D5
D2 D4
Gnd D3

62512 SRAM (32 pins, 1-16, 32-17) A18 +5V
A16 A15
A14 A17
A12 /WE
A7 A13
A6 A8
A5 A9
A4 A11
A3 /OE
A2 A10
A1 /CS
A0 D7
D0 D6
D1 D5

621024 SRAM (32 pins, 1-16, 32-17) NC +5V A16 A15 A14 CS2 A12 /WE A7 A13 A6 A8 A5 A9 A4 A11 A3 /OE A2 A10 A1 /CS1 A0 D7 D0 D6 D1 D5 D2 D4 Gnd D3

These would need to be edited to match [s]style and[/s][i]done[/i] format of the existing Wiki article. They're based on the
